Everything you need to know to turn bonus bets into guaranteed cash
💡 What Is Promo Bashing?
Australian bookmakers hand out bonus bets and promo offers to attract new sign-ups and keep existing customers betting. Promo bashing (also called bonus bet conversion) is the process of turning those "free" bonus bets into real, withdrawable cash by hedging - placing an opposing bet so you profit no matter which side wins.
There are two ways to hedge:
vs Betfair (Lay Betting)
You place the bonus bet on a bookmaker (back bet), then lay the same outcome on Betfair Exchange. If your selection wins, the bookmaker pays out but Betfair takes your liability. If it loses, Betfair pays you. Either way you lock in a profit.
Bookie vs Bookie
You place the bonus bet on one bookmaker, then bet on the opposite outcome at a second bookmaker. No exchange account needed, but conversion rates are usually lower.
✅ What You Need
- Bookmaker accounts - Sign up with AU-licensed bookmakers. The more you have, the better odds you can find. This tool supports: Sportsbet, Ladbrokes, Neds, PointsBet, TAB, TABtouch, Unibet, Betr, BetRight, BoomBet, and PlayUp.
- Betfair Exchange account (recommended) - Gives you the best conversion rates. Sign up at betfair.com.au. You'll need enough funds in your Betfair account to cover the lay liability.
- Bonus bets / promo offers - Sign-up offers, reload bonuses, multi boosts, whatever the bookmakers give you. Keep an eye on your email and app notifications.
- Enough bankroll for hedging - You'll need real money in your Betfair account (or second bookmaker) to place the hedge bet. This isn't lost - it's returned when the bet settles.
- Know your bonus type - Check if your bonus bet is SNR (Stake Not Returned - you only get the winnings, not the stake back) or SR (Stake Returned - you get the stake + winnings). Most AU promos are SNR.

🚀 Step-by-Step: Using the Bonus Basher
- 1Open the Bonus Basher - Click "Bonus Basher!" in the sidebar or from the card above.

- 5Enter your bonus amount - Type in the value of your bonus bet (e.g. $100).
- 6Set your Betfair commission - Default is 5%. Check your Betfair account for your actual rate (it may be lower if you have discount rates).
- 7Select your bonus type - Pick SNR (Stake Not Returned) or SR (Stake Returned). If you're unsure, it's almost always SNR.
- 8Hit "Scan Now" - The tool fetches live odds and calculates the best conversion opportunities. Results are sorted by conversion rate - best deals at the top.
- 9Read the card - Each result shows you exactly what to do: which bookmaker to back on, what odds, where to lay/hedge, how much to stake, your liability, and your guaranteed profit.
- 10Place both bets FAST - Odds move quickly. Open the bookmaker and Betfair side by side. Place the back bet first (bookmaker), then immediately place the lay bet (Betfair). Double-check the lay stake and odds match.
- 11Wait for the event to settle - Once the game finishes, one side pays out and the other side loses. Either way, you keep your guaranteed profit.
📝 Worked Example
You have a $100 SNR bonus bet on Sportsbet and a Betfair account with 5% commission.
Melbourne Victory vs Sydney FC
Back: Melbourne Victory @ 3.50 on Sportsbet (bonus bet)
Lay: Melbourne Victory @ 3.60 on Betfair Exchange
Lay Stake: $69.25
Liability: $180.05
Guaranteed Profit: $65.82
Conversion: 65.8%
What you do:
1. Place the $100 bonus bet on Melbourne Victory at 3.50 on Sportsbet
2. Lay Melbourne Victory on Betfair for $69.25 at 3.60 (you need $180.05 in your Betfair account for liability)
What happens:
Sportsbet pays you: $100 × (3.50 − 1) = $250 (bonus stake not returned)
Betfair lay loses: −$180.05 (liability)
Net: $250 − $180.05 = +$69.95
If Melbourne Victory loses:
Sportsbet: $0 (bonus bet lost - no real money lost)
Betfair lay wins: $69.25 × (1 − 0.05) = +$65.79
Net: +$65.79
Either way you walk away with roughly $66–$70 in real cash from a $100 bonus bet. That's promo bashing.
💎 Tips for Better Results
- Aim for 60%+ conversion - Anything above 60% is great. Below 50% is usually worth waiting for a better opportunity.
- Close odds = higher conversion - The closer the back odds and lay odds are to each other, the more you keep. Look for tight markets.
- Lower odds convert better - Odds around 2.00–4.00 typically give the best conversion rates. Very high odds (10.00+) give poor conversions.
- Act fast - Odds change constantly. When you find a good conversion, place both bets within seconds of each other.
- Use the spreadsheet button - Track every conversion in a spreadsheet so you know your total profit over time.
- Check Betfair liquidity - Make sure there's enough money available on Betfair at the lay odds shown. If there isn't, the next best lay price might be higher.
- Don't bet on events starting imminently - If a game is about to start, the odds can shift rapidly and you might not get both bets placed in time.
