Wozniacki said there was plenty to be pleased with regarding her performance. She will face 32 seed Slovakian Dominika Cibulkova in next match.

Fourth seed Venus Williams has staged a remarkable comeback, overcoming injury to win her way through to the third round of the Australian Open.

A seven-time Grand Slam champion, Williams was forced to call for an injury timeout after losing the first set. She then battled back from a groin injury to oust Czech Sandra Zahlavova 6-7 (6-8) 6-0 6-4.

"This is probably the most acute one I've had," Williams said. "In recent times it's been one of the toughest ones for sure but I just wanted to stay on court and survive.

"Obviously I wasn't able to play at my exact level so I had to play smarter and hang tough."

She will face German Andrea Petkovic next.

The 11th-seeded Henin, who took the Australian title in 2004, served beautifully throughout the match to completely control the second round encounter.

She defeated Britain's No.1 Elena Baltacha 6-1, 6-3 in 61 minutes to set a meeting with Russian Svetlana Kuznetsova on Friday' s third round.

Meanwhile, World No. 11 and recent Medibank International champion, Li Na from China has cruised through to the third round at Australian Open 2011 with a 6-3, 6-2 victory over Russian Evgeniya Rodina.

She will next face unseeded Barbora Zahlavova Strycova of the Czech Republic, who put an end to Australian Jelena Dokic's Australian Open 2011 campaign after beating the Australian 7-6(3), 6-1.
