Australian Betting Glossary: 150 Terms Explained

Australian betting has three overlapping vocabularies: racing jargon inherited from British turf language, sports betting terminology largely imported from the US, and advantage-play vocabulary that grew up around exchanges and arbitrage. A punter fluent in one is often lost in another.

This glossary covers 150 terms across all three, defined the way they are actually used in the Australian market rather than the way an international dictionary would render them. Where a term means something different here than overseas, that is noted.

A

• Accumulator — a multi. British term, occasionally used in AU.
• All-up — Australian racing term for a multi across races, where winnings from one leg roll into the next.
• Ante-post — betting on an event well before final fields are declared. Your stake is lost if your selection does not run.
• Arb (arbitrage) — backing all outcomes of a market at different bookmakers so that the total implied probability is below 100%, locking in profit regardless of result.
• Asian handicap — a handicap market with no draw outcome, using quarter- and half-goal lines to split stakes across two lines.
• ATS (against the spread) — US term for line betting results.

B

• Back — to bet on something to happen. The default action at a bookmaker; the opposite of lay.
• Bankroll — the total capital you have allocated to betting, separate from living expenses.
• Bar — in racing, the price at which all unlisted runners are quoted ("20 bar").
• Barrier — a horse's starting gate position. Inside barriers are generally advantageous over short trips.
• Best of the best (BOB) — a promotion paying the better of tote or fixed odds.
• Betting exchange — a marketplace matching backers against layers, taking commission on net winnings instead of building margin into the price.
• Blowout — a large drift in price, or a lopsided result.
• Bonus bet — a stake-not-returned free bet. Worth roughly 60-80% of face value if converted properly.
• Book — either a bookmaker, or the full set of prices in a market.
• Book percentage — the sum of implied probabilities across a market. Above 100% means margin; below 100% is an arb.
• Boxed — in exotics, selecting runners to finish in any order rather than a specified order.
• BSP — Betfair Starting Price. The reconciled exchange price at jump.

C

• Cash out — settling a bet early at a bookmaker-determined price. Almost always priced with additional margin.
• Chalk — the favourite.
• Closing line — the final price available immediately before an event starts.
• CLV (closing line value) — the difference between the price you took and the closing price. The main process metric for serious punters.
• Colours — silks worn by a jockey, identifying the owner.
• Commission — the percentage an exchange charges on net winnings. Betfair AU is typically 6.5% on racing markets.
• Correlated parlay — a multi where legs are not independent. The basis of same-game multis.
• Cover — to win against the handicap line.

D

• Dead heat — a tied result. Stakes are divided proportionally, reducing your effective payout.
• Decimal odds — the Australian standard. $2.50 returns $2.50 per $1 staked including stake.
• De-vig — to strip bookmaker margin from a set of prices to reveal fair probabilities.
• Dividend — the payout on a tote bet, declared after the event.
• Drift — a lengthening price.
• Dutching — backing multiple outcomes in the same market with stakes proportioned so every winning outcome returns the same amount.

E

• Each-way — two bets in one: half on the win, half on the place.
• Edge — your expected profit as a percentage of turnover.
• EV (expected value) — the average result of a bet if it could be repeated infinitely. Positive EV means the price is better than the true probability warrants.
• Exacta — picking first and second in exact order.

• Exposure — the maximum you can lose on a position.

F
