Why these four sports round out the Australian calendar
AFL and NRL dominate the Australian winter, cricket and racing carnivals dominate the summer, but tennis, basketball, golf and motorsport fill in the gaps year-round with their own dedicated betting audiences. None of these four sports has quite the same single dominant domestic competition that AFL or NRL enjoys - instead, each blends a local Australian element (the Australian Open, the NBL, the Australian Grand Prix, the Supercars Championship) with a much larger overseas or global calendar that licensed Australian operators also cover extensively.
That mix means this guide covers genuinely different market structures across four sports in one place, rather than a single deep dive into one competition. Read the section relevant to the sport you follow, and note that - consistent with every other guide on this site's Australia section - every market described here is a pre-match proposition, given Australia's prohibition on online in-play sports betting.
Tennis: the Australian Open and the ATP/WTA calendar
The Australian Open, held annually in Melbourne every January, is Australia's own Grand Slam and comfortably the single biggest tennis betting event of the Australian calendar, drawing far more attention from casual and dedicated bettors alike than any other tennis event held on Australian soil. Because tennis has no possibility of a draw - the sport's scoring and tiebreak systems are specifically designed to always produce a winner - match-winner betting in tennis is always a straightforward two-way market, simplifying the core betting decision relative to sports that need to account for a draw outcome.
Set betting, predicting the exact set score a match will finish on, and total games, an over/under market on the combined games played across the match, add depth beyond the basic match-winner market, while outright tournament winner markets function as pre-match futures bets covering the entire event from the first round through to the final, similar in principle to the outright markets described for cricket series and football tournaments elsewhere in this site's Australia coverage.
Beyond the Australian Open, the broader ATP and WTA tour calendar runs almost year-round, and licensed Australian operators typically extend coverage well past the four Grand Slams into the Masters 1000 and equivalent WTA-level events, giving dedicated tennis followers a consistent weekly betting product outside the major tournament windows.
Basketball: NBL and NBA
The National Basketball League (NBL), Australia's top domestic basketball competition, runs through the Australian spring and summer months, offering a local basketball betting product distinct from the NBA's own separate season. The NBA, played primarily during the Australian autumn and winter months given its US-based October-to-June calendar, draws substantial additional Australian betting interest on top of the NBL, reflecting the global reach and media coverage of the American league.
Handicap (points) betting is the central basketball market for both competitions, working the same way in Australia as it does in basketball betting generally: a set number of points is added to or subtracted from a team's final score before settlement, creating a more balanced betting line against a clear favourite than a straight match-winner price would offer. Total points (over/under) and player-performance markets - points, rebounds and assists for individual players - round out the core basketball offering, with the NBA in particular supporting deep statistical player markets given the volume of tracked data the league produces on every player, every game.
| Competition | Season timing | Typical Australian bettor profile |
|---|---|---|
| NBL | Australian spring/summer | Local club followers |
| NBA | Broadly aligned with US season (Australian autumn/winter) | Broad international basketball audience |
Golf: outright and each-way markets
Golf's large tournament fields - commonly well over 100 players in a standard PGA Tour or DP World Tour event, and similarly sized fields in Australia's own major tournaments - make outright tournament winner betting a naturally long-odds proposition, even for the strongest favourites in the field. This is exactly why each-way betting is so central to how golf is actually bet: half the stake backs a player to win outright, and half backs them to finish inside a defined number of top places, paid at a fraction (commonly 1/4 or 1/5) of the win odds if they place but don't win.
The Australian Open golf tournaments (men's and women's, distinct from the tennis Grand Slam of the same name) and other local PGA Tour of Australasia events give Australian bettors a domestic golf betting product, while major overseas tournaments - the four global majors and the Ryder Cup, played using match-play format rather than standard stroke-play scoring - draw the heaviest golf betting volume of the international calendar, similar to the pattern described for golf each-way betting in this site's other country-specific golf coverage.
Head-to-head (matchup) betting, pairing two named players from the same field and pricing which of the two will finish with the better score, offers a way to sidestep golf's large field entirely and bet on a more contained two-way outcome, similar in structure to tennis match-winner betting despite golf's fundamentally different tournament format.
Motorsport: Supercars and Formula 1
The Supercars Championship, Australia's premier domestic motorsport competition, and the Australian Grand Prix, held annually in Melbourne as part of the global Formula 1 calendar, anchor local Australian motorsport betting interest, sustained by the country's strong historical connection to both categories.
Race winner is the most direct motorsport market, betting on which driver crosses the finish line first. Pole position, betting on the fastest qualifying time rather than the race result itself, is a distinct market from race winner, since the fastest qualifier doesn't always convert that advantage into a race win. Championship winner markets - for either the Supercars or Formula 1 drivers' and constructors' championships - function as season-long outright bets, typically carrying longer odds early in a season and shortening progressively as results eliminate contenders or consolidate a clear favourite.
Head-to-head driver markets, betting on which of two named drivers finishes ahead of the other in a specific race, offer a way to bet on a more contained outcome than the full field, similar in principle to head-to-head matchup betting in golf. Podium finish markets, betting on whether a named driver finishes in the top three, sit between a straight race-winner bet and a full-field outright, giving bettors a middle-ground option for drivers considered strong contenders without being the outright favourite.
Weather and track conditions play an outsized role in motorsport betting relative to most other sports covered on this site. A sudden rain shower during a Formula 1 race, for instance, can dramatically reshuffle the competitive order based on tyre strategy and driver skill in changed conditions, which is part of why pre-match motorsport markets tend to build in wider margins than a comparably confident favourite would carry in tennis or basketball.
Pre-match-only wagering across all four sports
As explained throughout this site's Australia coverage, online in-play sports betting is prohibited under the Interactive Gambling Act, and this applies fully to tennis, basketball, golf and motorsport. A licensed ACMA-listed operator can offer extensive pre-match markets across all four sports - match winner, outright tournament and championship markets, handicaps, totals - locked in before play begins, but cannot legally offer Australian customers online in-play betting once a match, round or race is underway.
This is worth flagging specifically for tennis and basketball, since both sports have particularly deep in-play betting markets in jurisdictions where that product is legally available - point-by-point tennis markets and possession-by-possession basketball markets are common products in some other countries covered elsewhere on this site, but they are not part of the legal Australian online wagering market. Australian bettors following this guide should treat every market described here as a pre-match proposition, consistent with the framing used across our main Australia betting guide.
Decimal odds across tennis, basketball, golf and motorsport
Odds across all four sports are displayed in decimal format on Australian licensed platforms, the same convention used across every sport and racing product covered on this site. A tennis match-winner price of 1.50 reflects an implied probability of roughly 66.7% before the operator's margin, while golf outright winner prices are typically much longer given large tournament fields - a leading player might be priced at $15.00 or higher to win a major outright, reflecting the genuine difficulty of predicting a winner from a field of well over 100 players.
For a full breakdown of how decimal odds convert to implied probability and how bookmaker margin factors into the price offered, see our main Australia betting guide, which covers the decimal odds framework applicable across every sport on licensed Australian platforms, including each-way golf calculations.
Common mistakes across these sports
- Betting a golf outright winner without considering each-way terms, missing out on a place-portion payout that would have covered a strong top-10 finish that fell short of an outright win.
- Ignoring surface specialism in tennis - a player's clay-court form does not reliably translate to hard courts, which is the dominant surface at the Australian Open.
- Backing a heavy favourite's straight match-winner price in a lopsided basketball fixture when a handicap line offers meaningfully better value for the same underlying view.
- Assuming pole position and race winner are effectively the same bet in motorsport, when the fastest qualifier frequently fails to convert that advantage into an actual race win.
- Overlooking how NBL and NBA seasons run on different calendars, and betting on player-performance markets without confirming which specific competition and current roster you're actually looking at.
- Building large multi bets across several different sports in this guide without accounting for how differently each sport's variance behaves - golf and motorsport outright markets, in particular, carry much higher variance than a typical basketball or tennis match-winner bet; see our general parlays guide for how compounding risk works across multiple selections.
Treat wagering as entertainment, set a fixed budget before the event, and use BetStop or other account controls if you want to stop or reduce access.
Safer gambling across these sports
Concentrated events - the Australian Open's two-week window, a Formula 1 or Supercars race weekend, a golf major played across four consecutive days - can encourage more frequent betting activity in a short period than these sports' otherwise spread-out calendars would typically produce. That's worth factoring into deposit and time limits specifically during those concentrated windows, rather than applying the same budget approach used for a sport's quieter, more spread-out weeks.
As explained throughout this site's Australia coverage, licensed online and phone wagering operators cannot accept credit-card or cryptocurrency deposits, and must participate in BetStop, Australia's national self-exclusion register covering all licensed online and phone wagering providers in a single registration.

Frequently asked questions
Can I bet on tennis, basketball, golf or motorsport while the event is in progress in Australia?
No. Online in-play sports betting is prohibited under Australia's Interactive Gambling Act, and this applies to all four sports. Every market offered by licensed Australian operators for these sports is pre-match, locked in before play begins.
How does each-way golf betting work?
An each-way bet splits your stake into two equal parts: half backs a player to win outright at full odds, and half backs them to finish inside a defined number of top places, paid at a fraction (commonly 1/4 or 1/5) of the win odds. Standard weekly events typically pay fewer places than major championships, where bookmakers often extend place terms.
What's the difference between pole position and race winner in motorsport betting?
Pole position is a bet on which driver sets the fastest qualifying time, determining grid position for the race. Race winner is a bet on which driver actually finishes first, which is a separate outcome since the fastest qualifier doesn't always win the race itself.
Does the NBL have as much market depth as the NBA on Australian platforms?
Generally not to the same extent. The NBA's global following and the sheer volume of statistical data it produces typically support deeper player-performance markets than the NBL, though core markets like match winner, handicap and totals are usually well covered for both competitions.
Why is the Australian Open the biggest tennis betting event in Australia?
Because it's Australia's own Grand Slam, held annually in Melbourne every January, drawing far more domestic betting attention than any other tennis event held on Australian soil, including from casual bettors who don't follow the ATP/WTA tour closely the rest of the year.
Are odds for these four sports displayed differently from other sports in Australia?
No. All four follow the same decimal odds format used across Australian sports and racing betting generally, with the same underlying logic of implied probability and bookmaker margin.
