Quick answer: Real-money online blackjack is not legally offered to people in Australia. Under the Interactive Gambling Act 2001, it is illegal for a company to provide online casino games (including blackjack) to Australians, and the offence sits with the operator, not the player. Offshore sites still target Australians, but you get no Australian protection if something goes wrong. Free games with no money, like ours, are legal.
Please note: this page is general information, not legal advice. We reviewed it on 30 September 2026. Laws change, so check the ACMA website or ask an Australian lawyer about your own situation.
We get this question more than any other. I am not a lawyer, so we stick to what the law and the regulator say publicly, and we point out where the rules are about to change.
The short version
- Online casino games for money (blackjack, roulette, pokies, online poker) cannot legally be offered to people in Australia.
- Playing is not the offence. The law targets the companies that provide or advertise these services.
- Licensed online betting is legal (for example sports and racing wagering and lotteries from Australian-licensed providers).
- Blackjack at a land-based casino is legal for adults 18+.
- Free blackjack with no money (no deposits, no prizes) is not gambling for money.
What the Interactive Gambling Act 2001 says
The Interactive Gambling Act 2001 (IGA) is the federal law that covers gambling online. In plain terms:
- Prohibited services: online casino games played for money, including blackjack, cannot be provided to customers in Australia.
- Advertising: advertising prohibited gambling services is also banned (Part 7A of the Act), and the ban reaches those who publish the ads, not only the operators.
- Enforcement: the Australian Communications and Media Authority (ACMA) enforces the Act. Since November 2019 it has asked internet providers to block illegal gambling sites, and by 20 August 2026 it had blocked 1,788 illegal casino and affiliate websites.
So why do offshore sites still show up for Australian players? Because they operate from other countries and ignore the Act. That does not make them legal here, and a licence from another country (such as Curaçao) does not change that.
What changes with the Gambling Reform Act 2026
The Interactive Gambling Amendment (Gambling Reform) Act 2026 received Royal Assent on 26 August 2026. Most of its main parts start on 1 January 2027. Based on the Act as passed, the key changes are:
- Payment blocking: payments to illegal offshore operators are to be blocked.
- New duties for search engines, internet providers and app stores to act against illegal gambling services.
- Fast takedown notices: advertising and links to illegal gambling can be subject to 24-hour removal notices.
- Penalties for publishers who advertise illegal online casinos.
- An anti-avoidance rule that has applied since 26 August 2026.
What does that mean for a player? In my view, depositing and withdrawing with offshore sites is likely to get harder from 2027, and sites you used before may simply disappear. The exact detail will depend on how ACMA applies the new powers, so watch its announcements.
Player vs operator: who breaks the law?
| Who | What the law says |
|---|---|
| A person in Australia playing online blackjack | Not an offence under the IGA |
| A company offering online blackjack to Australians | Prohibited, with penalties enforced by ACMA |
| A website advertising those services | Advertising prohibited services is banned; publishers face penalties |
| An Australian-licensed betting company (sports, racing) | Legal, but cannot offer online casino games |
"Not an offence" does not mean "safe". Read the next section before you decide anything.
The real risks of offshore blackjack sites
We read player complaints from Australians on public complaint sites. The same problems come up again and again:
- Withdrawals that stall. Payouts are delayed for months or refused on "technical" grounds.
- Identity checks (KYC) that never end. Some Australian banks issue statements only quarterly, which does not fit a site demanding a recent one.
- Winnings voided over bonus terms the player says they never accepted.
- Nowhere to complain. No Australian regulator oversees these sites, so there is no local body to take your dispute.
- No BetStop coverage. The national self-exclusion register covers licensed Australian wagering providers only, not offshore casinos.
- Payment problems from 2027, once payment blocking starts.
Having analysed bonus terms for ten years, I can tell you the fine print is where most of these disputes start. On an unlicensed site, that fine print is also the only rulebook you get.
What you can do legally

Do you pay tax on blackjack winnings?
For most people, no. The ATO generally treats gambling winnings of recreational players as not taxable (and losses as not deductible). Professional gamblers can be treated differently. This is general information only, so check with the ATO or a tax adviser if gambling is a big part of your income.

Frequently asked questions
Is online blackjack legal in Australia?
Companies cannot legally offer real-money online blackjack to people in Australia under the Interactive Gambling Act 2001. Playing it is not an offence for the player, but offshore sites are unregulated here and you have no local protection.
Can I get in trouble for playing online blackjack in Australia?
The IGA targets operators and advertisers, not players. The practical risks for players are unpaid winnings, voided accounts and payment problems, not prosecution.
Is a Curaçao-licensed casino legal in Australia?
No. A foreign licence does not permit a company to offer online casino games to Australians. The IGA applies regardless of where the operator is licensed.
Does BetStop block online casinos?
No. BetStop covers licensed Australian online and phone wagering providers. Offshore casinos are outside it.
What changes on 1 January 2027?
Most of the Gambling Reform Act 2026 starts then, including payment blocking for illegal operators and new duties for search engines, internet providers and app stores.
Is free online blackjack legal?
Yes. A game with no deposits, no prizes and no cash-outs is not gambling for money. That is how our game works.
