The top seeds continue to progress at the Australian Open Tennis Championships in Melbourne with women's top seed Caroline Wozniacki and former men's champions Rafael Nadal and Roger Federer all winning their third round matches.

Wozniacki, who is yet to win a grand slam title, beat Monica Niculescu of Romania in straight sets, while third seed Victoria Azarenka beat German Mona Barthel.

Nadal eliminated the last qualifier Lukas Lacko of Slovakia, while Federer beat big-serving Croatian Ivo Karlovic.

Defending women's champion Kim Clijsters is in action tonight against Daniela Hantuchova.
