When the footy finishes, Australian wagering doesn't stop; it changes shape. Summer brings Test cricket and the Big Bash, January brings the Australian Open to Melbourne, and basketball and the A-League run right through. The pricing principles are the same as for AFL and NRL, but three things work very differently:
• How a result is defined. Draws, rain, retirements and extra time all need their own settlement rules.
• Where the main market is. For many of these events, the biggest money is overseas, and Australian prices follow it.
• When information arrives. Time zones mean some prices move while Australia sleeps.
Here's the summer, sport by sport.
Cricket: Tests, one-dayers and the Big Bash
Cricket: Tests, one-dayers and the Big Bash
The Boxing Day Test. The Test starting at the MCG on 26 December is one of the biggest days on the Australian sporting calendar: on 26/12/2025, day one of the Ashes Test drew 94,199 people, a record crowd for cricket at the MCG. A Test match can end four ways: a win for either side, a draw or, very rarely, a tie. That makes the match market a three-way market with an unusual feature: the draw price depends heavily on the weather.
How that works in practice:
• Before the match, the draw price reflects the forecast and how the pitch is expected to behave over five days.
• During a rain-affected Test, time lost makes a result less likely, so a draw becomes more likely. Pre-match markets anticipate that from the forecast. Online wagering closes once play starts.
• The toss and the decision to bat or bowl can move prices significantly on a pitch expected to deteriorate.
One-day and T20 cricket, including the Big Bash League, almost always produce a result. Rain-shortened matches are decided under the Duckworth-Lewis-Stern method, which recalculates targets. Each operator's rules say how DLS results, "no result" matches and ties (including super overs) are settled.
Where the money is. For international series, the deepest wagering markets are in other cricket-following countries, and Australian operators watch them closely. For the Big Bash, local operators have more say over their own prices.
Tennis: the Australian Open in January

How the price is formed. Tennis has a well-understood statistical structure: a player's chance of winning a match can be built up from their chance of winning points on serve and on return. Most models start there and adjust for surface, recent results and fitness. At Melbourne Park, the hard courts and the summer heat both feature in that adjustment.
What moves the price: the draw release, scheduling (a player coming off a long five-set match), and injury news.
The retirement rule. If a player retires injured mid-match, operators' rules differ: some settle bets once a set is completed; others void bets unless the match is finished. This causes more confusion than almost anything else in tennis wagering, and it's settled entirely by the operator's own rules.
Integrity. Professional tennis has a dedicated integrity body, the International Tennis Integrity Agency (ITIA), which works with wagering operators and regulators to monitor suspicious wagering patterns.
A real enforcement case. Tennis also produced one of the ACMA's clearest in-play findings. In a report finalised on 22/09/2025, the ACMA found a licensed wagering operator had accepted 426 online in-play bets on 32 tennis matches between 16/02/2024 and 25/06/2025, affecting 354 customers. The ACMA accepted that most bets were caused by a system error at a third-party provider, fixed on 18/07/2025, but still found a breach of the Interactive Gambling Act 2001: under the Act, the operator is responsible for compliance whatever the cause.
Basketball: NBL at night, NBA in the morning
Basketball: NBL at night, NBA in the morning
The NBL runs through the Australian summer, with games in local prime time. Local operators price these markets themselves, and liquidity is smaller than for the big codes.
The NBA is played in US time zones, which means games usually finish during the Australian morning. Team news and injury reports also land during the US day, so NBA prices often move while Australia is asleep.
What moves the price most: player availability. In the NBA, a star listed as resting or questionable can move a line by several points, and that news often lands close to tip-off. Lines (spreads) and totals are the core markets, both well suited to statistical models because basketball has so many possessions per game.
Football: the A-League and the overseas leagues
Football: the A-League and the overseas leagues
A three-way market. A draw is a normal football result, so the standard match market has three outcomes: home, draw, away. The margin is spread across all three.
What "full time" means. Most match markets settle after 90 minutes plus stoppage time, excluding extra time and penalties. "To qualify" and "to lift the trophy" markets are different: they include extra time and penalties. Reading the market name is the simplest way to avoid a surprise.
Local versus global. For the A-League, Australian operators set their own prices, but pools of money are smaller, so prices can move further on less money. For the English Premier League and the Champions League, the main markets are overseas and Australian prices usually move with them.
Handicaps. Football lines often use half-goal or quarter-goal handicaps (often called Asian handicaps) to remove the draw or split a stake across two lines. Settlement rules are set by each operator.
Why the margin depends on the shape of a market
Why the margin depends on the shape of a market
Across all of these sports, one pattern holds: the more possible outcomes a market has, the bigger the operator's margin tends to be, because each extra outcome is another place to shade the price.
A worked comparison (our illustration):
So a $3.40 in a football match and a $3.40 in a golf market aren't the same kind of number. Each carries the margin of the market it sits in.
The rule that applies to every one of them

Whatever the sport, licensed Australian providers can't take online bets once the event has started. That's why online markets close at the toss, the first serve or kick-off. The Rules explains the law; the tennis case above shows how it's enforced.
