Lock in margins from bookmaker pricing gaps
Sherwood scans 7+ Australian bookmakers every 20 seconds. When two books disagree on odds, you can back both sides for a locked-in margin — when you get both legs on at posted prices. Unlike alert-only tools, Sherwood is designed to keep you betting sustainably across multiple books.
Arbitrage is not literally risk-free. Odds move, stake limits apply, legs can be voided, and bookmakers reserve the right to cancel palpable errors. Past scanner performance does not guarantee future results. 18+ only.

Explore the dashboardThree ways to profit
Arbitrage is just the beginning
Sherwood covers the three core advantage betting strategies used by serious Australian bettors. Each one extracts value differently — together they compound your edge.
Guaranteed profit, zero risk
When two bookmakers disagree on odds enough, you can back both sides and lock in a profit regardless of the outcome. Sherwood finds these pricing gaps across 7+ Australian bookmakers every 20 seconds.
Positive expected value, sized for growth
Not every edge is an arb. When our models detect odds that are mispriced relative to true probability, Kelly criterion sizing lets you grow your bankroll while managing variance.
Convert promos into real cash
Australian bookmakers hand out bonus bets constantly. Sherwood calculates the optimal conversion strategy — back odds, lay sizing, and exchange commission — to turn free bets into withdrawable profit.
Profit calculator — worked example
Model what your inputs would return
Enter your stake size, arb frequency, and assumed margin — the calculator returns the arithmetic result if every leg fills at the posted price. The 2–3% margin range reflects what our scanner typically surfaces across Australian books, but the output is a model of your inputs, not a forecast of your results.

Worked example — not a forecast
Figures are calculated arithmetic from the inputs above assuming both legs always fill at the posted prices. Real outcomes depend on opportunity volume, execution speed, stake limits, voided or partially-filled legs, palpable-error cancellations, and bookmaker restrictions. The 2.5% margin and 3 arbs/day you selected are adjustable assumptions, not guarantees. Not financial advice.

Modelled profit
+$2,250
An arbitrage pays out regardless of which side wins only if both legs execute at the posted prices for the planned stakes. If one leg voids, is partially filled, is repriced, or a bookmaker limits the stake, the position becomes a one-sided bet with ordinary loss risk.
Modelled 7-day scenario
How the three strategies combine on paper
A worked example of $1,000 flat staking across arbitrage, Kelly +EV, and bonus-bet turnover over a plausible 7-day slice. Figures are hardcoded illustrative scenario data — not a backtest of live scanner output — used to show relative contribution and the kind of variance +EV introduces.

Methodology & known risks
Data source: Hardcoded illustrative scenario, not a backtest of live scanner output. Staking model: $1,000 flat stake per arbitrage and bonus-turnover bet; half-Kelly sizing for +EV bets with 58% modelled hit rate. Known risks that can erase modelled returns:price movement between leg-one and leg-two placement, partial fills, stake limits, voided or resettled legs, palpable-error cancellations, bookmaker account restrictions, bonus-bet T&C changes, and variance on the +EV strategy (negative days are expected and shown). Past or modelled performance does not guarantee future results. 18+ only. Not financial advice.
