Strong field for Aus Open

Three-time champion Roger Federer heads the men's draw, while world number one and the 2004 winner Justine Henin leads the women.

The only omission from the top 100 women is Russia's world number 44 Vera Dushevina, who has been forced to withdraw with a right-foot injury.

"It's fantastic news to know that all of the world's best tennis players are coming to Melbourne in January for the Australian Open," Australian Open tournament director Craig Tiley said.

"The field is sprinkled with genuine superstars, rising stars and Australians, which will no doubt lead to some brilliant tennis. At this stage, it's the strongest field in the event's history and we're sure this will equate to one of the most exciting tournaments yet."

The men's field will be completed by 16 qualifiers and eight wildcards, while the women's field has 12 qualifiers and eight wildcards.

The women's draw includes five former champions in Henin, Venus and Serena Williams, Amelie Mauresmo and Lindsay Davenport.

Among the men, Federer, Thomas Johansson and Marat Safin are all former winners. The tournament takes place in Melbourne from January 14-27.
