Is online gambling legal?
Interactive Gambling Act 2001
Who regulates gambling
Crypto gambling tax
Credit and crypto banThe industry calls it the "grey market": a peculiar but stable arrangement where online casinos break the law of Australia by allowing Australians to play at them, while the Australians break no law by playing at them. The arrangement exists outside the Interactive Gambling Act 2001 (and all amendments to it), which prohibits the suppliers of online casino games to Australia while remaining silent about the customers, the Australians.
Why this page matters
The existence of the grey market, and the peculiar way Australian players must engage with online casinos based outside Australia, explains most of the oddities you notice: foreign licences, changing web addresses, crypto-accepting casinos, and the complete absence of anyone official in Australia to complain to should anything go wrong.
Why international casinos serve Australia anyway
Australians lose more money to gambling than any other nation on earth. At roughly A$1,527 per adult per year, the amount lost across all forms of gambling is the highest in the world, and that figure is only an approximation; industry estimates place the money lost to unlicensed international online casinos at about A$3.9 billion a year. There is no legal way to serve that demand for online casinos: the Act created no licence for them, and no Australian government intends to.
The penalties for breaking Australian law only exist on paper for an industry that owns nothing in Australia. There is no local entity affiliated with these online casinos that anyone could fine for breaking the law. So hundreds of operators around the world take the demand from Australians and ignore the unenforceable penalty for serving them; the cost of doing business is little more than having a domain blocked and setting up a fresh one every so often.
The licences they actually hold
The online casinos that serve Australians do not operate under Australian licences, but most of them do hold a licence from a foreign regulator: the Curacao Gaming Control Board, Anjouan Gaming, the Kahnawake Gaming Commission and a few others. The quality of these bodies ranges from excellent to wholly inadequate. Some of the older, more respected regulators have a real reputation for letting players lodge complaints and getting money returned when they are wronged. Others simply take a fee and hand over a certificate of licensing. And some of the casinos serving Australians put no licence on their website at all.
The licence ladder
The quality of these licensing authorities ranges from excellent to poor. Near the top sit the Kahnawake Gaming Commission and the Curacao Gaming Control Board. In the middle sits Anjouan Gaming. At the bottom are the casinos that "licence" themselves in Costa Rica, which has no gaming regulator at all. Where an operator's authority sits on that scale should decide how much money you are willing to leave in its casino account.
There is really only one thing to weigh when choosing an online casino in this industry: the quality of the licence its foreign regulator has issued. Our casino reviews exist largely to check exactly that, casino by casino.
The three layers of the market
From the player's perspective, there are three separate layers of online gambling available to Australians. The top layer is licensed gambling based in Australia, which does not allow online casinos at all; it limits online sports and racing betting to NT and state licences. The middle and bottom layers are both made up of international casinos licensed outside Australia, and the quality between those operators varies a lot. The bottom layer is the international casinos with no named operator, no licence number, and domain registrations younger than most Australians' last haircut.
Australian law makes no distinction between the middle and bottom layers. Both are illegal to provide, and both are blocked from Australians by the ACMA. The one real difference is practical, in whether your withdrawals actually arrive: the middle layer pays out, while the bottom layer often does not. That distinction lives in practice, not in law, and working out which layer a given site belongs to is the job of the casino reviews.
What ACMA blocking means for you
Unable to reach the operators themselves, the ACMA simply makes their websites unreachable to players instead. 1,708 gambling and affiliate websites have been blocked through Australian internet service providers (ISPs) since November 2019, as of May 2026, and around 220 online gambling operators have abandoned the Australian market since 2017.
The blocked websites respond by creating what are called "mirror domains", usually the same brand name with a number bolted on, such as adding 1, 2 or 3. Once the primary domain is blocked, players simply move to the newly created, not-yet-blocked mirror. Three simple rules cover it for players:
- A blocked site is a formally-identified illegal service. ACMA publishes the list; a brand on it has been through the regulator's evidence process. Treat that as information, not noise.
- Your balance does not vanish when a block lands, but reaching the cashier may require the operator's newest domain. Serious operators maintain continuity across mirrors; fly-by-night ones use the shuffle to disappear. That difference is worth knowing before you deposit, not after.
- Blocks also hit affiliate and review sites, so the information layer around this market churns too.
What the exits look like
These exits are nothing new; they have been happening in Australia for years. When the amended Interactive Gambling Act 2001 came into force in 2017, several of the largest international operators, PokerStars and 888 among them, left the country within months of enforcement beginning. Casinos have kept leaving ever since, roughly 220 operators gone, and some have even published reports explaining their exit. Most of them, like the international operators that still dominate the market, sit under a handful of very large corporate groups.
The fact that casinos keep abandoning the Australian market and changing their domain names does not mean their appetite for Australian players has changed. More often, their corporate groups have simply decided it is more profitable to leave the market than to keep serving Australian customers through the domain shuffle.
The protections you give up
This is the honest, complete truth about the international casinos that serve Australians, and any site that neglects to mention it is trying to sell you something. Playing at one means playing without:
- Dispute resolution. No Australian regulator, ombudsman or tribunal can order an international casino to pay you. A withheld withdrawal is between you, the operator, and whatever complaint process its foreign licence provides.
- BetStop coverage. The national self-exclusion register binds licensed Australian wagering services only. Your BetStop registration is invisible to international casinos; if you rely on self-exclusion, you need per-site exclusion requests and blocking software on top.
- Advertising and fairness rules. Australian standards on bonus advertising, inducements and terms do not apply. A "200% bonus" at an international site means whatever its own terms say, which is why we read them so closely.
- Payment recourse. Card chargeback paths are largely absent because deposits run through crypto. A mistaken or regretted crypto transfer has no reversal mechanism at all.
It is true that any specific online casino may turn out badly for the player, but the reality of the international casino market is that the most well-regarded, reputable operators pay out winnings to their players very regularly.
The information layer churns too
One of the less-appreciated features of this market is that the government's blocked list includes not just the casinos but the sites that promote them; plenty of affiliate and review sites are blocked too. Add the expired-domain spam that infests casino search results, where sites that once belonged to a casino now push inaccurate junk, and information about these casinos becomes unstable and often worthless. The only sources worth trusting are the ones that show their reasoning for a ranking, name the evidence behind it, and tell you how often they update it.
How to operate inside the grey market sensibly
- Choose operators that name their company and publish a licence number; skip any that publish neither. Verify through reviews that check, including ours.
- Read withdrawal terms before depositing: caps, KYC triggers and bonus fine print are where disputes start. Every one of our reviews carries a red-flags section for exactly this.
- Keep balances small and withdraw often. At a casino the law cannot reach, your exposure is whatever sits in the account.
- Test new sites with a small deposit and an early withdrawal before committing real money.
- Set your own limits before playing. The tools the licensed market would impose do not exist here, so you are the regulator.
Will the grey market ever go away?
Australia has not licensed online casinos, and enforcement against international operators is unlikely to ever be airtight, so the future of both sits with the licensed wagering on sports and racing instead. The government keeps tightening the licensed sector: banning various payment methods for gambling and restricting how those services can advertise. Those measures are covered in a separate article, our credit and crypto ban explainer. The future for online casinos, then, is likely to stay exactly as it is: a prohibited industry that is both available and blocked, whose operators spin up new domains to dodge the blocks. The complete legal picture behind the Interactive Gambling Act sits in the main Australian gambling law guide.

Grey market casinos FAQ
What is a grey market casino?
An online casino, licensed outside Australia, that accepts players from a country where providing casino games is prohibited but playing them is not. For Australian players, that describes every single online casino, since none can be licensed here.
Is it illegal to play at a grey market casino in Australia?
No. The Interactive Gambling Act creates no criminal offence for players of online casinos, and no player has ever been prosecuted under it. The operator is the party acting against Australian law.
Why do casino websites keep changing their address?
The ACMA has Australian internet service providers (ISPs) block access to illegal gambling websites, and in response those sites set up numbered mirror domains for players to move to. That cat-and-mouse cycle between the regulator and the casinos is the enforcement system the Act created, with the operators simply taking their turn each time.
What happens to my money if a casino gets blocked?
Only the website address is affected by the block. The casino company itself, and players' account balances, are left untouched. What actually decides whether you should keep using a site and depositing money is the operator's reputation, which is the thing to settle before you deposit, not after.
Are winnings from a grey market casino legal to keep?
Yes. Nothing in the Act makes winning money from online gambling an offence, and for recreational players those winnings are exempt from tax. If the winnings came as cryptocurrency, later disposals of those coins create capital gains for the player, and those rules are covered in our crypto gambling tax guide.
