The Australian Open can look like two tournaments at once: a best-of-five test for men in singles, a best-of-three contest for women, and different scoring rules again in doubles. The basic format is straightforward once you know how the draws, sets and tiebreaks fit together.
How the Australian Open singles draw works
The men’s and women’s singles draws each start with 128 players. The draw is a knockout: lose a match and you are out; win seven matches and you are champion. There are no home-and-away series or group stages.
Players reach the main draw in several ways. Most earn direct entry through their world ranking, while others receive a wildcard from the tournament. Qualifying is held before the main draw: players who win three qualifying matches can claim one of the 16 qualifying places. The field also includes a small number of places reserved for players in special circumstances, such as a protected ranking.
Thirty-two players in each singles draw are seeded, based mainly on their ranking. Seeding is designed to keep the highest-ranked players apart in the early rounds, though it does not guarantee an easy path. An unseeded player can still face a seed in the first round, and a tough draw can bring top contenders together earlier than expected.
| Singles round | Players left at the start | Matches to win the title from this point |
|---|---|---|
| First round | 128 | 7 |
| Second round | 64 | 6 |
| Third round | 32 | 5 |
| Round of 16 | 16 | 4 |
| Quarterfinals | 8 | 3 |
| Semifinals | 4 | 2 |
| Final | 2 | 1 |
The main tournament usually runs for 15 days, beginning on a Sunday. First-round singles matches are spread over three days, then the rounds progress toward the semifinals and finals in the second week. The exact daily schedule can vary from year to year.
Singles match scoring
Men’s singles matches are best of five sets. The first player to win three sets wins the match, so a match may finish 3–0, 3–1 or 3–2. Women’s singles matches are best of three sets: two sets win the match, making the possible results 2–0 or 2–1.
Within a set, a player usually needs to win six games and lead by two. At 6–6, the players play a tiebreak. In a standard tiebreak, the first to seven points wins, but they must be ahead by two. So a tiebreak might finish 7–4 or 9–7.
The final set has a special rule. If it reaches 6–6, players play a 10-point match tiebreak, again needing a two-point margin. This applies to men’s and women’s singles. It replaced the old approach of continuing the final set until someone won by two games, which could produce very long matches. A final-set score might read 7–6(8–6), where the bracketed figures show the tiebreak points.
That rule makes the finish more predictable, but the pressure is still intense: at 6–6 in the final set, one short burst of points can decide a match that has lasted for hours. Players have to reset quickly after a demanding set, while also knowing that a small run of errors can end their tournament.
How doubles and mixed doubles differ
The men’s and women’s doubles events each have a 64-team draw. Matches are best of three sets, with a 10-point match tiebreak used in place of a third set if the teams split the first two. Doubles also uses no-ad scoring: at deuce, the next point decides the game. That can make a single return, volley or serve-and-volley play especially consequential.
Mixed doubles has a 32-team draw, with one woman and one man on each team. It is also best of three, with a 10-point match tiebreak in place of a third set and no-ad scoring. Because the match tiebreak is shorter than a full set, teams can be only a few points away from victory even after a closely contested match.
| Event | Draw size | Match format |
|---|---|---|
| Men’s singles | 128 players | Best of five sets; 10-point tiebreak at 6–6 in the final set |
| Women’s singles | 128 players | Best of three sets; 10-point tiebreak at 6–6 in the final set |
| Men’s and women’s doubles | 64 teams each | Best of three; match tiebreak in place of a third set |
| Mixed doubles | 32 teams | Best of three; match tiebreak in place of a third set |
Qualifying, court conditions and the schedule
Qualifying is a separate knockout tournament played before the main draw. It gives players who are outside the direct-entry cutoff a chance to earn a place by winning three matches. The stakes are high: a qualifier may arrive in the main draw with several competitive matches already under their belt, but also with less recovery time than a player who entered directly.
Australian Open matches are played on outdoor hard courts. Heat can be a major factor, especially during daytime sessions, and the tournament uses a heat policy that can affect play when conditions become severe. The main stadium courts have retractable roofs, so play can continue there during rain or extreme heat. A roof changes the conditions too: with the court enclosed, wind becomes less of a factor, which can alter how players serve and strike the ball.
Matches are scheduled in day and night sessions. A ticket for a particular session does not necessarily mean one specific match; the order of play can shift with match length, weather and other delays. A five-set singles match may run much longer than a quick straight-sets win, which is one reason the day’s later start times are not always exact.

Final Thoughts
The Australian Open’s format combines a simple knockout path with a few important differences between events. Singles players face seven rounds, men’s matches can stretch to five sets, and every singles final set is decided by a 10-point tiebreak at 6–6. Doubles uses shorter matches and no-ad scoring, so momentum can turn quickly. Knowing those details makes it easier to follow the draw—and to understand why a match that looks close on paper can be decided by just a handful of points.
