2025 Australian Open Tennis Online Betting

Last year, the relatively unknown Jannik Sinner was the surprise Australian Open men’s singles champion. Sinner, age 23, went on to win the 2024 US Open championship for his second career Grand Slam title. The Italian resident of Monte Carlo was even ranked #1 in the world for a brief week in June. Indeed, a star was born at the Australian Open. Sinner is a player to watch for years to come.

On the women’s side, Aryna Sabalenka was the 2024 Australian Open champion. It was a repeat championship for Sabalenka, who won her first career Grand Slam title at the 2023 Australian Open. Last year she also took the US Open championship.

For 2025, the Australian Open will take place from January 14-28 at Melbourne Park.

The first Grand Slam event on the tennis betting schedule is the Australian Open.  As one of the four Grand Slam events on the tennis calendar, the Australian Open will draw massive betting activity both on the future market and on the daily matchup odds.

As is the case with March Madness and the pro sports playoffs, Grand Slam tennis events such as the Australian Open are big draws for casual bettors who normally do not pay attention to tennis.  With that in mind, tennis has a name-brand element on the board, like all other sports.

Until recently, Novak Djokovic was the biggest name in the game and drew most of the casual sector support.  That was also the case on the women’s side with Serena Williams, whose popularity has not been matched since her retirement.

Sinner ended 2024 as the number one ranked men’s player and opened as the betting favorite for the 2025 Australian Open.  Also drawing strong support for this year’s event are Carlos Alcaraz, Novak Djokovic, Alexander Zverev, and Daniil Medvedev.

On the women’s side, Sabalenka finished 2024 as the top-ranked female and opened as the betting favorite to win the 2025 Australian Open. Iga Swiatek, Coco Gauff, and Elena Rybakina also have strong support.

Of course, it comes as no surprise that Novak Djokovic is the all-time leading champion of the Australian Open, with ten singles titles in the Open Era.  Before last year, Djokovic won four of the last five Australian Opens.  The lone exception was in 2022 when another one of the greats of the game, Rafael Nadal, claimed the title.

Djokovic is followed by Roger Federer (6), Andrea Agassi (4), and Mats Wilander (3) on the all-time Australian Open victory list.

Since the open era that began in 1969, on the men’s side, the United States leads with 14 championships, followed by Serbia (10), Switzerland (7), and then Australia and Sweden (6).

On the women’s ledger, the great Serena Williams is the all-time leader with seven Open Era championships.  Following Williams are Margaret Smith Court, Evonne Goolagong, Steffi Graff, and Monica Seles, with four titles each.

In the open era, which began in 1969, the United States leads with 18 championships, followed by 11 for Australia and five for Germany.

The women’s side has shown much greater parity and unpredictability than the men’s portion.  The women have seen four different winners in the past four years and seven different champions in the past eight years.

Australian Open Winners (2000)

The Australian Open was played twice in 1977, once in January and once in December. The tournament was not held in 1986 when it switched permanently from a December event to a January event.

Most Career Men's Wins (Open Era)

Novak Djokovic has the most wins at this tournament in the Open Era, with Roger Federer next with six victories. Roy Emerson reigned supreme in the amateur era with five straight titles in the 1960s.

Most Career Women's Wins (Open Era)

*Court won a total of 11 Australian Open titles, though seven of her championships came in the amateur era.

There is a reason Australia's secondary court behind Rod Laver Court is named after Margaret Court. She was dominant in her country's tournaments throughout the 1960s and 1970s, winning the Aussie Open seven straight times in the 1960s and four more times during the Open Era.
