Is Arbitrage Betting Legal in Australia? (2025 Laws)

Arbitrage betting — also known as “arbing” — is a strategy that guarantees profit by taking advantage of differing odds between bookmakers. While it might sound too good to be true, it’s not a scam or illegal. But if you’re an Australian punter wondering whether arbitrage betting is legal in 2025, here’s everything you need to know.

Is Arbitrage Betting Legal in Australia?

Yes, arbitrage betting is legal in Australia. There are no laws prohibiting individual bettors from placing arbitrage bets. As long as you’re betting with licensed Australian bookmakers, you’re not breaking any rules.

That said, bookmakers don’t like arbers, and many include terms in their user agreements that allow them to:

Limit your account
Void bets deemed to exploit clear pricing errors
Restrict access to promotions or bonus markets

So, while it’s legal, it’s not always welcome — and most serious arbers use multiple accounts to spread their activity.

What Is Arbitrage Betting?

Arbitrage betting involves placing bets on all possible outcomes of an event across multiple bookmakers where the odds allow a profit, regardless of the result.

Example:

Let’s say you find these odds for a tennis match:

Bookmaker A: Player 1 to win @ 2.10
Bookmaker B: Player 2 to win @ 2.10

If you stake $100 on each outcome, your guaranteed return would be $210, with a total outlay of $200 — locking in a $10 profit, no matter who wins.

How Do Aussies Find Arbitrage Opportunities?

Most successful arbers in Australia use arbitrage software or alert services that scan markets across dozens of bookies in real time. These tools help identify:

Odds discrepancies
Price changes
Mispriced markets (especially in lower leagues or niche sports)

However, many of these tools include offshore sportsbooks, which Australian punters cannot legally access. Stick to regulated, Aussie-facing bookies for legal compliance.

Important Legal Notes for Australian Punters

The Interactive Gambling Act 2001 regulates online betting in Australia
Arbitrage betting is not banned or even mentioned in the legislation
You must be 18+ and verified to bet legally
Using automated bots or software to place bets may breach a bookmaker’s terms, even if not illegal

Always read the T&Cs of each sportsbook — especially clauses around bonus abuse or “non-recreational” betting behaviour.

Which Aussie Bookmakers Are Best for Arbing?

To find profitable arbitrage bets, you need a mix of fast-moving and slower-moving bookies. Here’s how some stack up:

Bet365 – Sharp pricing, but limits arbers quickly
Sportsbet – Good market depth, but actively monitors behaviour
BlueBet – Less aggressive with limits, ideal for smaller bets
PlayUp – Competitive fixed odds across racing and AFL
TopSport – Strong for higher-stakes arbers but risk of account restriction

Some punters also include Betfair, the exchange platform, to balance arbitrage positions using lay bets.

Tips to Avoid Getting Limited

Don’t Always Bet Maximums – Small, varied stakes draw less attention
Mix in Recreational Bets – Occasionally place multis or novelty wagers
Avoid Always Winning – If your account shows only profit, you’ll raise flags
Use Multiple Accounts – Spread your activity (within legal and ethical limits)
Withdraw Strategically – Don’t always cash out immediately after a win

Remember: while the strategy is legal, bookmakers are private businesses and can limit or restrict accounts at their discretion.

Final Word: Legal but Not Limitless

Arbitrage betting is 100% legal in Australia, and smart punters can use it to generate consistent returns. But the real challenge isn’t legality — it’s sustainability. You’ll need to stay sharp, adapt to market limits, and avoid detection if you want to keep your edge.

It’s not a get-rich-quick scheme, but for disciplined Aussies, it can be a clever, calculated way to bet with an advantage.
