Yes. Arbitrage and matched betting are legal in Australia. They exploit differences in odds between bookmakers — no laws prevent this. Bookmakers may limit accounts of consistent winners, which is why we track multiple platforms.
For matched betting, yes — Betfair is the exchange you use to lay bets and eliminate risk. For pure arbitrage (backing two bookmakers against each other), you don't need Betfair.
Most bookmaker promos require a qualifying deposit of A$10–$50. To work through all 22 promos and maximise the A$755+ value, a starting bank of around A$500–$1,000 is ideal.
It's the guaranteed cash you can lock in from a bonus, after accounting for qualifying costs and lay commissions. A A$100 free bet typically extracts ~A$75 in guaranteed profit using matched betting.
