Frequently Asked Questions
What is a betting exchange?
A betting exchange (like Betfair) lets you bet against other punters instead of a bookmaker. You can back (bet for) or lay (bet against) outcomes. The exchange takes a small commission on winning bets.
What exchange is best for Australians?
Betfair is the most popular exchange in Australia with the deepest liquidity for Australian sports and racing. Smarkets offers lower commission (2% vs 5%) but has less liquidity on AU markets.
