World number one and two-time reigning champion Novak Djokovic is the top seed for the upcoming Australian Open, with Roger Federer seeded second.
Andy Murray has been confirmed as the third seed.
The British number one, who won his maiden grand slam at last year's US Open and yesterday retained his Brisbane Open title, is looking to win at Melbourne Park for the first time after finishing runner-up in 2010 and 2011.
David Ferrer is fourth with Tomas Berdych fifth. Rafa Nadal, the world number four, pulled out of the tournament last week through illness.
The top women's seed is Victoria Azarenka, followed by Maria Sharapova, Serena Williams, Agnieszka Radwanska and Angelique Kerber, matching the WTA world rankings.
The Australian Open takes places between January 14-27.
