A multi (multi bet or parlay) combines two or more separate selections into one bet, with the odds multiplied together — every leg must win for the bet to pay out. A same game multi (SGM) combines multiple bet types from a single match (e.g. first tryscorer plus total points). A futures bet is a wager on a longer-term outcome — such as a premiership or Group 1 winner — settled weeks or months later. All three are higher-variance products offered by ACMA-licensed Australian bookmakers.
How a standard multi bet is priced
A multi combines two or more independent selections into a single bet. The total price is calculated by multiplying the decimal odds of each leg together. For example, two legs priced at $2.00 and $3.00 combine to $6.00 (2.00 × 3.00). A $10 multi at those odds returns $60 if both legs win — but if either leg loses, the entire multi is void and returns nothing, even if the other leg won.
This compounding is what makes multis attractive for a small stake chasing a large return, and also why they carry materially higher risk than single bets. Adding legs increases the total price rapidly, but also multiplies the probability of the whole bet failing — each additional leg is another independent chance to lose the entire stake.
Same game multis (SGMs): how they differ from standard multis
A same game multi (SGM) combines multiple bet types from within a single match — for example, a specific player to score first, the match winner, and total points over/under, all in one bet. Unlike a standard multi across different events, SGM legs from the same match are not statistically independent: some outcomes are correlated (a team winning comfortably makes a high individual player points tally more likely, for instance).
Because of this correlation, bookmakers price SGMs using their own combined-odds models rather than a simple multiplication of each leg's standalone price — the displayed SGM price is usually shorter than multiplying the individual market prices would suggest. Correlated-leg combinations (for example, backing the same player for both first tryscorer and most tries) are commonly restricted or priced down by operators precisely because the legs are not independent events.
Futures betting: premierships, Group 1 races and long-range markets
A futures bet is a wager on an outcome that will not be settled until well after the bet is placed — a premiership or grand final winner months out from finals, a Group 1 racing feature such as the Melbourne Cup ante-post, or a competition's leading goal-kicker across a season. Futures odds move continuously as form, injuries and team news develop, and the price you take today may differ significantly from the price closer to the event.
Futures markets typically carry the bookmaker's largest overround (built-in margin) because outcomes are harder to price accurately over a long horizon. Some operators pay futures bets out early under specific conditions (for example, once a team is mathematically eliminated or has won the underlying event) — always check the specific product terms before placing a long-range bet.
- Futures prices move continuously — early markets can offer better value before public money shortens the favourites
- Overround is typically higher on futures than on single-match or single-race markets
- Some operators offer early payout on futures under specific conditions — check product terms
- Funds are tied up until the market settles, sometimes months later
Each-way bets: how they combine with multis
An each-way bet — common in horse racing — splits a stake equally between a Win bet and a Place bet on the same runner, paying the Win portion if the horse wins, and only the Place portion if it places but does not win. Each-way multis exist on some racing products but are comparatively rare and priced conservatively, because the each-way condition adds a further layer of correlated risk across multiple legs. Most Australian bookmakers do not offer each-way legs within a standard sports multi.
Whichever bet type you use, only wager money you can afford to lose, and treat multis, SGMs and futures as higher-variance products rather than a reliable staking strategy.

Frequently asked questions
How is the price of a multi bet calculated?
The decimal odds of each leg are multiplied together. Two legs at $2.00 and $2.50 combine to $5.00 (2.00 × 2.50). Every leg must win for the multi to pay out — if any leg loses, the whole bet is void.
Why is a same game multi (SGM) priced differently to multiplying the individual odds?
Legs within the same match are often statistically correlated — for example, a team winning comfortably makes a big individual points tally more likely. Bookmakers use their own combined pricing models for SGMs rather than a simple multiplication, and heavily correlated leg combinations are commonly restricted or priced down.
What is a futures bet in Australian sports betting?
A futures bet is a wager on a longer-range outcome — such as a premiership winner or a Group 1 race months out — settled well after the bet is placed. Futures markets typically carry a higher built-in margin than single-match or single-race bets because the outcome is harder to price accurately that far out.
Can I place an each-way bet inside a multi?
Some operators offer each-way legs within racing multis, but it is not universal and is priced conservatively due to the added correlated risk. Most standard sports multis do not support each-way legs — check the specific bet-slip options on your operator's platform.
