Best First Deposit Bonus Casinos in Australia for 2026

The first deposit bonus is the only time an online casino pretends it actually wants to give you something. It isn’t charity. It’s a customer acquisition cost dressed up as a welcome mat. For Australian players in 2026, that mat still sits on an offshore porch. The Interactive Gambling Act 2001 makes it illegal for an operator based in Australia to offer real-money online casino games. So every brand claiming to be an “Australian casino” and offering a first deposit bonus is either licensed overseas or operating from a jurisdiction that doesn’t care much about Canberra’s opinion.

That doesn’t mean you can’t claim the bonus. You can. The ACMA blocks dodgy sites and fines Australian companies that provide services to them, but individual players aren’t prosecuted for signing up at Curacao-licensed casinos. The best offers come from established offshore brands that process AUD, run proper customer support, and don’t vanish when you request a withdrawal.

This guide ranks the ten strongest first deposit bonus casinos available to Australian players in 2026. The bonuses are compared by real value, not by the size of the number on the banner. A 200% match with 45x wagering is often worse than a 100% match with 25x. I’ve done the arithmetic so you don’t have to.

How we ranked the best first deposit bonus casinos in Australia

If you read only the marketing copy, every casino has the “best first deposit bonus casino Australia 2026” award. I ignore the copy. I look at four things.

No one metric decides it. The ranking below is a blend of bonus size, terms, brand history, and Australian player feedback across forums and complaint boards.

The 10 best first deposit bonus casinos in Australia for 2026

Here’s the full table. The “Bonus” column lists what the operator advertises for the first deposit as a type. Exact caps change more often than Melbourne weather, so I focus on structure: match percentage, free spins count, and whether the bonus is split across deposits.

Casino First Deposit Bonus Wagering (Typical) Standout Feature
PlayAmo 100% match bonus + 100 free spins 30x bonus Fast crypto withdrawals
Fair Go Casino 100% match bonus 25x bonus + deposit Long AU track record
Joe Fortune Welcome package with match + free spins 35x bonus Strong AU support
Ignition Casino 100% match bonus for casino 25x bonus Poker and casino hybrid
Ricky Casino Welcome package with match + free spins 40x bonus Large game library
Bizzo Casino Welcome package with match + free spins 40x bonus High max bet allowed
SkyCrown Casino 100% match + free spins 30x bonus Crypto focus
Hell Spin Casino Match bonus + free spins 35x bonus Aggressive promos
Woo Casino Match bonus + free spins 40x bonus Loyalty program
National Casino Match bonus + free spins 40x bonus Regular tournaments

PlayAmo

PlayAmo is the default answer for Australian crypto users. The Curacao-licensed operator has been around since 2016, and it shows. Withdrawals in Bitcoin or Litecoin often land within an hour. The first deposit bonus is a 100% match with 100 free spins on selected slots. Wagering sits at 30x the bonus, which is below the industry average for offshore sites. The game library runs past 3,500 titles, so you won’t run out of pokies to clear the playthrough.

The free spins drip out at 20 per day for five days. That’s a retention mechanic, not a loyalty reward. If you want all spins upfront, you’ll be disappointed. But the match itself is solid. Minimum deposit for the bonus is usually A$20. AUD deposits via Neosurf or bank card work fine, but crypto gets you faster payouts and sometimes a small extra match.

One catch: play through the bonus on live dealer games and contributions drop to 5%. That’s standard. PlayAmo isn’t trying to hide it, but you need to read the tables.

Fair Go Casino

Fair Go has been serving Australian players since before the Great Barrier Reef got bleached. It’s an RTG shop, so the game choice is pokies, keno, and table games with old-school graphics. The first deposit bonus is simple: 100% match, no free spins, and wagering of 25x bonus plus deposit. If you deposit A$100, you wager A$5,000 before cashing out. That’s tighter than it looks because RTG slots are high variance.

Payouts come mainly via bank transfer or bitcoin. Bank transfer takes up to five banking days, which is slow by 2026 standards. Bitcoin cuts that to about 24 hours. Fair Go’s appeal is predictability. It has been around forever, it pays, and it doesn’t run 700% welcome packages that vanish when you try to withdraw. The bonus isn’t flashy. It’s just honest in a sector where honesty is rare.

If you prefer a casino that doesn’t pretend to offer a “VIP” experience with a $10 deposit, Fair Go is your pace.

Joe Fortune

Joe Fortune is the Australian-facing brand that gets mentioned in the same breath as PlayAmo. The welcome offer is a package across your first deposits, with the first deposit getting a match and free spins. Exact percentages shift, so check the cashier. Wagering is typically 35x bonus, which is reasonable but not generous.

Support is the main reason Australian players stick with Joe Fortune. Live chat answers fast, and withdrawal requests are processed without the classic “we need KYC documents again” dance. Bank transfers take three to five banking days. Crypto payouts are quicker. The game library leans toward pokies, but there are enough blackjack and roulette tables to satisfy casual players.

One note: the first deposit free spins are often tied to a specific slot like A Night with Cleo or Fairy Dust Forest. If you hate the assigned game, the spins lose value. Always check which slot you’re being handed.

Ignition Casino

Ignition is the poker player’s casino. The same account runs both poker and casino, and the first deposit bonus for casino is a 100% match with wagering of 25x bonus. That’s one of the lowest wagering requirements in this ranking. If you deposit A$100, you get A$100 in bonus and need to wager A$2,500 on eligible games. For slots, that clears quickly. For blackjack, contributions drop to 5%, making the effective wagering far higher.

Australian players have used Ignition since the Bodog split. Payouts via bitcoin are fast; bank transfers are slower. The casino section is smaller than PlayAmo or Bizzo, but the game quality is better than average. The poker bonus is separate and generally terrible for casual players, so stick to the casino side if you’re after a first deposit bonus.

Ignition doesn’t run daily free spin promos. The first deposit bonus is the main event, and it’s fair if you play slots.

Ricky Casino

Ricky Casino is one of the newer operators that exploded onto Australian-facing forums around 2023. It’s a multi-provider casino with a huge library and a welcome package that spans several deposits. The first deposit gets a match and free spins, with wagering at 40x bonus. That’s higher than I like, but the high max bet during wagering makes up for some of it. Most casinos limit you to A$5 or A$6 per spin while clearing; Ricky allows more, so aggressive players can clear faster if they choose high-variance slots.

Withdrawals process quickly for crypto, often within hours. Bank cards take longer. The site is designed for mobile, and the support team understands Australian slang and banking quirks. The first deposit bonus sometimes requires a code sent by email, so check your spam folder before depositing.

Ricky Casino’s weakness is its loyalty program. It reads like a cheap motel with a fresh coat of paint. The “VIP” perks are mostly small cashback and birthday bonuses. Don’t chase them.

Bizzo Casino

Bizzo Casino is another multi-provider giant with a first deposit bonus that includes a match and free spins. Wagering is 40x bonus, which matches Ricky. The game library is one of the largest available to Australian players, with thousands of pokies from 80+ providers. That matters because you want variety while clearing a 40x requirement.

Bizzo’s standout feature is its high max bet limit during wagering. Many casinos cap you at A$5; Bizzo allows significantly more. That speeds up the grinding process if you’re willing to play bigger. But bigger bets also mean faster variance, and you can burn through the bonus before you hit a feature.

Payouts are fine. Crypto withdrawals process in under an hour in most cases. Bank transfers take the usual three to five days. Customer support is responsive, but they do ask for KYC documents on first withdrawal, which is standard.

SkyCrown Casino

SkyCrown positions itself as the crypto-native alternative to PlayAmo. The first deposit bonus is a 100% match with free spins, and wagering is 30x bonus. If you deposit with Bitcoin or Tether, you may get a slightly better match or extra spins. The game library is huge, with a strong live dealer section from Evolution and Pragmatic Play.

Australian players like SkyCrown for fast cashouts. Crypto withdrawals usually land within an hour. Fiat withdrawals via bank transfer take several days. The site is mobile-friendly and supports AUD display, though your bank may block card deposits to offshore gambling merchants. Neosurf is a reliable workaround.

The one annoying habit: SkyCrown pushes its loyalty program on every login. The “VIP” levels are mostly cosmetic. Ignore them and focus on the first deposit bonus, which is genuinely competitive.

Hell Spin Casino

Hell Spin is the casino equivalent of a heavy metal album cover: loud, aggressive, and occasionally fun. The first deposit bonus is a match plus free spins, with wagering at 35x bonus. That’s mid-pack. The game library is large, and the slots selection includes many high-volatility titles that can clear wagering quickly if variance smiles.

Withdrawals via crypto are fast. Fiat payouts take longer. Hell Spin runs frequent reload bonuses and tournaments, but the first deposit offer is the main reason to sign up. The design is busy, and the pop-ups are distracting. You’ll click through five “bonus” banners before you reach the cashier. That’s by design.

On the plus side, the minimum deposit for the first deposit bonus is low, often A$15. That makes it a decent testing ground for players who don’t want to commit big money to a new brand.

Woo Casino

Woo Casino has been around since 2020 and built a reputation for a solid loyalty program and regular free spin offers. The first deposit bonus is a match plus free spins, with wagering at 40x bonus. It’s not the tightest, but the game selection and reliable payouts keep it in the top ten.

Woo’s loyalty system actually means something: you earn points that convert to cash, not just “VIP merch” no one wants. That’s rare. The casino processes crypto withdrawals quickly and bank transfers reasonably. Minimum deposit is usually A$15, which is low enough for a trial.

The main weakness is the wagering requirement on the first deposit free spins: winnings are often capped at A$100. That’s clearly stated in the terms, but many players miss it. Free spins are never a path to riches.

National Casino

National Casino is a multi-provider brand with a first deposit bonus that includes a match and free spins. Wagering is 40x bonus, fairly standard for this tier. The standout feature is the tournament calendar. National runs weekly slots races and blackjack challenges, which can offset the high wagering if you participate.

Withdrawals via crypto are quick. Fiat is slower. The game library is extensive, and the live casino section is better than average. Australian players report reliable support, though not as responsive as Joe Fortune or PlayAmo.

The first deposit bonus sometimes varies by deposit method: crypto deposits get a slightly higher match. That’s becoming common in 2026, and it’s worth considering if you’re comfortable with digital assets.

What actually counts as a first deposit bonus

Not every “welcome offer” is a first deposit bonus. Some casinos split it across your first three or four deposits. Others front-load it all on the first one. When I say “first deposit bonus casino Australia 2026”, I mean the offer you unlock the moment your first real-money deposit settles.

A classic first deposit bonus is a match. You deposit A$100, the casino adds A$100 in bonus funds. Then you have A$200 to play. The catch sits in the wagering requirement and the game contribution table.

Some operators call it a “casino first deposit bonus” and toss in free spins. Those spins usually unlock over several days, not all at once. If the banner says “100 free spins on first deposit”, read whether they drop in one hit or trickle out 20 per day. That changes the value. Slow-drip free spins are a retention tool, not a bonus.

Types of first deposit bonuses you’ll actually see

Match bonus. The casino matches your deposit by a percentage, usually 100% or 200%, up to a cap. The higher the match, the more bonus funds you get, but the cap limits the real value. A 200% match up to A$100 is worse than a 100% match up to A$500 if you deposit A$300.

Free spins. A fixed number of spins on selected slots. Usually valued at A$0.10 or A$0.20 per spin. Winnings from free spins are either credited as bonus funds with wagering or, less often, as real cash with no wagering and a max cashout.

No wagering bonus. Rare. You get bonus funds or free spins, and you can withdraw winnings without playthrough. The catch is almost always a low max cashout or a tiny bonus amount. Casinos aren’t running a soup kitchen.

Cashback on first deposit. A percentage of your losses on the first deposit is returned as bonus funds or real cash. Usually 10-20%, with a cap. This is less glamorous but sometimes more valuable than a match because the wagering is lower.

Wagering requirements: the real price of a first deposit bonus

Wagering is expressed as a multiplier. A 30x bonus wagering means you must stake 30 times the bonus amount before you can withdraw winnings from it. If you claim a A$100 bonus at 30x, you need to place A$3,000 in qualifying bets.

Some casinos apply wagering to bonus + deposit. A “25x bonus + deposit” on a A$100 deposit + A$100 bonus means wagering = (100+100) x 25 = A$5,000. That’s higher than 30x bonus-only. This is the difference between a cheap bonus and an expensive one.

Game contributions matter more than the headline number. Slots usually count 100%. Blackjack might count 5%. Roulette 10%. Video poker 20%. If you play blackjack, a 25x slots bonus with 5% blackjack contribution becomes effectively 500x. The math isn’t hard, but it’s deliberately hidden.

Here’s the information gain many guides miss: compare the effective wagering per dollar of bonus to the house edge. If a bonus has 30x wagering on slots with a 3% house edge, the expected loss from wagering is roughly 0.9 times the bonus amount. That means the bonus is slightly negative in EV before you factor in variance. If the wagering is 25x, expected loss is 0.75 times bonus. Add the deposit match and you’re often break-even. That’s why casinos can afford to “give” you money.

First deposit bonus no wagering: is it real?

Yes, but rare. A no wagering first deposit bonus lets you withdraw winnings from the bonus without meeting a playthrough requirement. The operator either caps the bonus small, limits max cashout, or restricts eligible games. It’s the casino’s way of saying “this is actually a cashback with extra steps.”

In Australia, the term “first deposit bonus no wagering” often appears in promotions for free spins. You deposit A$20, get 50 free spins, and whatever you win from those spins is yours, subject to a max cashout like A$100. That’s not a life-changing gift. It’s a trial-size product.

If you see a no wagering bonus with no max cashout and a big match percentage, read the terms twice. Then check the operator’s license and complaint history. Something is usually off.

First deposit free spins: how they work and what they’re worth

Free spins on first deposit are the most common add-on. You deposit, you get spins, and whatever you win goes into a separate balance. Most casinos set the spin value at A$0.10 or A$0.20. Fifty spins at A$0.10 is A$5 of wagering value. Compare that to a 100% match on A$50, which gives A$50 in bonus funds. Free spins alone rarely compete with a match bonus.

The value of free spins depends on two things: the slot they’re assigned to and the wagering on winnings. If you get 100 spins on a low-variance slot with 96% RTP, your expected return is roughly 96% of the spin value. That’s A$9.60 on A$10 of spins. But if winnings are subject to 40x wagering, the expected value drops further. Most free spin winnings aren’t worth chasing as a standalone reason to join a casino.

What free spins do well is extend your playtime and let you test new slots without risking your own money. If the first deposit bonus casino Australia 2026 offer includes a solid match and free spins, fine. If it’s only free spins, you’re being handed a free sample of toothpaste. Not harmful, but not exciting either.

Australian legal basics for first deposit bonus casinos

Australia doesn’t issue online casino licenses. The Interactive Gambling Act 2001 prohibits Australian-based operators from offering casino games online. The Australian Communications and Media Authority (ACMA) enforces this by blocking unlicensed offshore sites and fining companies that advertise them. But individual Australians can legally access offshore casinos. The law targets providers, not players.

This creates an odd grey area. You won’t find a “first deposit bonus casino Australia 2026” that is licensed by an Australian state regulator. Every operator in this guide holds an offshore license, typically from Curacao, Kahnawake, or Malta. Those regulators don’t offer the same protections as Australian consumer law.

If you have a dispute with an offshore casino, don’t expect the ACCC to ride in. Your recourse is the operator’s nominated ADR in Curacao or a forum complaint. Choose brands with a long history of resolving payout issues, not the newest banner with the biggest 300% match.

BetStop, the national self-exclusion register, applies to Australian-licensed wagering operators. Offshore casinos don’t participate. If you need to self-exclude from offshore casino play, you have to do it directly with each brand. That’s a gap worth knowing before you deposit.

How to evaluate a first deposit bonus in under 10 minutes

Run that checklist and you’ll discard 90% of offers before you even open an account.

Payment methods and minimum deposits for Australian players

Most first deposit bonuses require a minimum deposit, usually A$15 to A$30. The payment method also matters. Some casinos exclude e-wallets from bonus eligibility, while others offer higher matches for crypto deposits. Here’s how the common methods stack up in 2026.

Payment Method Typical Min Deposit Withdrawal Time Notes for AU Players
Visa/Mastercard A$10-A$20 1-3 banking days Some banks decline gambling transactions
Neosurf A$10 Not available for withdrawal Prepaid voucher, good for small deposits
Skrill/Neteller A$10-A$20 0-24 hours Often excluded from bonuses
Bank Transfer A$20-A$50 2-5 banking days Slow but reliable
Bitcoin/Ethereum A$20 equivalent 0-1 hour Fastest payouts, lower fees
Litecoin/Tether A$20 equivalent 0-1 hour Common at crypto-focused casinos

First deposit bonus mobile casino Australia: what changes

Mobile play doesn’t change the first deposit bonus mechanics. The offer is the same whether you sign up on desktop or mobile. But the experience of clearing wagering on a phone is different. Many Australian players use mobile as their primary device. The best first deposit bonus mobile casinos are the ones with a responsive site or a dedicated app, fast loading times, and a cashier that doesn’t freeze when you switch to a banking app.

PlayAmo, Bizzo, and SkyCrown work well on mobile. Joe Fortune has a native-style web app. Fair Go feels dated on a phone, but it functions. If you plan to clear a 40x wagering requirement on a 6-inch screen, stick to operators with clean mobile UX. Nothing kills a bonus hunt faster than a slot that crashes mid-spin.

Some casinos run mobile-only first deposit promos. Those are rare and usually small: an extra 20 free spins or a 50% match instead of 100%. Read the terms. Mobile exclusivity is not a reason to choose a worse bonus.

First deposit bonus slots: which games clear wagering fastest

Slots are the engine of first deposit bonus clearing. They count 100% toward wagering at almost every casino. That means your choice of slot matters for how fast you convert bonus funds into withdrawable cash. High-variance slots can clear wagering quickly if you hit a feature, but they can also burn through your balance in minutes. Low-variance slots clear more slowly but preserve your bankroll.

Look for slots with high RTP, 96% or above. Avoid progressive jackpots when clearing a bonus because they often have lower RTP and don’t contribute fully to wagering. Stick to games like Book of Dead, Legacy of Dead, Big Bass Bonanza, or classic fruit machines. The exact title matters less than the volatility and RTP.

Some casinos restrict certain slots from bonus play. Usually high-RTP games like Blood Suckers are excluded. If a slot has 98% RTP, the casino doesn’t want you clearing a bonus on it. That’s not a conspiracy; it’s just arithmetic.

First deposit bonus real money vs demo mode

A first deposit bonus only works with real money. You can’t claim a welcome bonus while playing in demo mode. The deposit is the trigger. Some players confuse free spins in demo mode with free spins on a real-money first deposit. The demo spins are worthless beyond testing the game. Real first deposit free spins are tied to a deposit and can produce withdrawable winnings, subject to wagering or caps.

If you’re new to online casinos, start with demo mode to learn the game mechanics. Then deposit and claim the first deposit bonus for real money. That sequencing saves you from wasting bonus funds on a slot you don’t understand.

Ignore any operator that offers a “first deposit bonus” without requiring a deposit. That’s a no deposit bonus, a different animal entirely. And usually a much smaller one.

The fine print no one reads: bonus codes, max cashout, and expiry

Every first deposit bonus has a terms page. Most players scroll past it. That’s how casinos get away with 45x wagering, A$50 max cashout, and 7-day expiry. The headline bonus is a marketing number; the terms are the actual product.

Check the maximum cashout. A 100% match that caps winnings at A$20 is a waste. Check the expiry. A 30x wagering requirement with a 3-day window is mathematically harder than a 40x with 30 days. Check the bonus code. If the casino doesn’t display it clearly, ask support before depositing. A forgotten code often voids the bonus, and support may not credit it retroactively.

Also look for “forfeitable” vs “non-forfeitable” bonus. Non-forfeitable means you can withdraw your deposit even while bonus wagering is incomplete. Forfeitable means you lose the bonus if you withdraw early. Most Australian-facing casinos use forfeitable bonuses. Know the difference.

First deposit casino promotions: what comes after the welcome offer

The first deposit bonus is just the opening move. Most casinos follow up with reload bonuses, free spin drops, and loyalty rewards. Australian players often ignore these, but they matter if you plan to stick with a brand. A casino with a great first deposit bonus but no ongoing promos is a one-night stand. A casino with a decent first deposit bonus and regular reload offers might be worth a relationship.

Joe Fortune and Woo Casino run consistent reload bonuses. PlayAmo has weekly free spin tournaments. Hell Spin sends more bonus emails than a spam folder. The quality varies. A 50% reload with 40x wagering is worse than no reload at all; it just tempts you to deposit more.

Before you cash in a first deposit bonus, look at the promotions calendar. If the operator only has one offer and it’s the welcome bonus, walk away. The best first deposit bonus casino Australia 2026 should be part of a broader bonus ecosystem.

First deposit bonus Australia: AUD banking and currency conversion

Australian players deal with three banking realities. First, many banks block card deposits to offshore gambling merchants. Second, AUD deposits are often converted to USD or EUR, and conversion fees eat into your bonus. Third, withdrawal times vary wildly depending on the method.

Choose casinos that display AUD as a native currency. PlayAmo, Fair Go, Joe Fortune, and Bizzo do. That avoids a two-step conversion on every bet. If a casino doesn’t support AUD, your A$100 deposit might become US$62 after fees, and your bonus is calculated on the converted amount. That’s a hidden tax.

Crypto deposits avoid currency conversion entirely, but they introduce volatility. If Bitcoin drops 10% between your deposit and withdrawal, your bonus has to overcome that before you break even. Not a problem for quick sessions, but if you hold crypto for weeks, the math changes.

How to claim a first deposit bonus in five minutes

Step one: pick a casino from the ranking above. Step two: create an account using accurate details. Step three: navigate to the cashier and select your deposit method. Step four: check if a bonus code is required. If yes, enter it. Step five: make the deposit and verify the bonus appears in your balance before you play.

If the bonus doesn’t credit automatically, contact support immediately. Don’t start playing and then complain later because the wagering clock has already started ticking. Take a screenshot of the bonus terms before you deposit. If a dispute arises, that screenshot is your evidence.

Claiming a first deposit bonus is not the same as activating a “free” gift. You are entering a contractual obligation to wager. The casino is not your friend. But if you follow the steps, the process takes less than five minutes.

New casinos with first deposit bonuses worth watching in 2026

The established brands dominate this guide, but a few newer operators deserve a mention. Katsubet, 7Bit Casino, and Playzilla all launched within the last few years and offer first deposit bonus packages with match percentages above 150%. Their wagering requirements sit between 35x and 45x, which is slightly worse than the top ten here. The bigger concern is track record. A casino that has been paying Australian players for five years beats one that opened in 2025 and runs a 300% sign-up offer.

King Johnnie is another newer RTG casino targeting Australian players. Its first deposit bonus is a match plus free spins with wagering around 30x. Payouts are slow by modern standards, but the brand has avoided major complaints so far. If you want to test a smaller operator, keep your deposit small and your expectations lower.

Ignore the “new casino” hype cycles. The first deposit bonus casino Australia 2026 market is overcrowded. A new brand with a huge welcome package is usually just trying to buy market share before its payment processor gets cut off.

Methodology: how I selected these first deposit bonus casinos

No operator paid for inclusion. I considered every brand that accepts Australian players, either legally offshore or in the grey zone. The main criteria were: license and regulatory history, first deposit bonus terms, Australian player feedback, withdrawal speed, game library depth, and customer support quality.

I gave extra weight to operators with a track record of honoring withdrawals over five or more years. A Curacao license means almost nothing on its own, but a Curacao license plus a five-year payout history means more than a Malta license with a three-month history of dodging requests.

The bonus rankings are current as of early 2026 but exact percentages and free spin counts change without notice. Always check the cashier and the specific terms before you deposit. If an offer looks too good to be true, it is.

Responsible gambling

First deposit bonuses are designed to get you to deposit and play. That’s fine if you treat them as a paid entertainment expense with a slight chance of profit. It’s not fine if you chase losses or believe a “VIP” program will save you. Set a deposit limit before you sign up, use session reminders, and never gamble with money you need for rent.

Offshore casinos don’t participate in BetStop, so you have to self-exclude manually at each brand. Most offer self-exclusion in the account settings or via support. Use it if you need it. There’s no shame in walking away from a “free” bonus that costs you more than it gives.

Is it legal for an Australian to claim a first deposit bonus at an offshore casino?

Yes, for the player. The Interactive Gambling Act targets operators and advertisers, not individuals. You are not breaking Australian law by signing up and depositing at an offshore site. The risk sits with the operator and, in practice, with you if the casino refuses to pay.

What is a good wagering requirement for a first deposit bonus?

Anything under 30x bonus-only is decent in 2026. A 25x bonus requirement is good. If wagering applies to bonus plus deposit, look for 20x or lower. Slots players can handle higher multipliers; table game players should avoid anything above 30x because contributions are often tiny.

Can I withdraw my first deposit bonus immediately?

Almost never. The bonus is locked until you complete wagering. Some no wagering free spins allow immediate withdrawal of winnings, but usually with a low max cashout. Always check whether the “bonus” is withdrawable cash or just bonus funds with a playthrough leash.

Are first deposit free spins better than a match bonus?

Not always. Free spins often have lower wagering or no wagering, but the winnings are capped and the spin value is small. A A$0.10 spin on 50 free spins gives A$5 of wagering potential. A 100% match on A$100 gives A$100 in bonus funds. Compare expected value, not headline count.

Do all first deposit bonuses require a bonus code?

No. Many modern casinos credit the first deposit bonus automatically when you opt in at the cashier or tick a box. Some loyalty-based casinos still require a code emailed after signup. If a code is mandatory and not displayed clearly, assume the promotion is either outdated or selectively offered.
