World No.1 Iga Swiatek leads the entry list for next year's Australian Open, which is based on the WTA rankings of the week beginning Dec. 5.

Reigning Roland Garros and US Open champion Swiatek is one of 13 current or former Grand Slam winners who have entered the first major of 2023, which begins on Jan. 16 in Melbourne. The Pole, who reached her first Australian Open semifinal this year, will be bidding to add a fourth Grand Slam title to her haul so far.

Three former Australian Open champions are in the line-up -- Victoria Azarenka (2012-13), Naomi Osaka (2019, 2021) and Sofia Kenin (2020) -- as well as three former Australian Open runners-up, Petra Kvitova (2019), Garbiñe Muguruza (2020) and Danielle Collins (2022). This year's champion, Ashleigh Barty, retired from professional tennis in March and will not defend her title.

Additionally, seven-time major winner Venus Williams will compete as a wild card.

Nineteen of the world's Top 20 are entered, with the only exception being the provisionally suspended Simona Halep.

Kenin, currently ranked No.240 and on the comeback trail after an injury-struck season, is one of 11 players using a special ranking to enter the main draw.
