Alicia Molik is brimming with confidence heading into this month's centenary Australian Open following her unbeaten run at the Hopman Cup in Perth this week.

Australia was forced to pull out of the mixed teams tournament for the third time in four years after Mark Philippoussis tore his groin in two places.

A foot injury to Molik led to Australia's withdrawal from last year's final, while the host nation also retired in 2002 after Lleyton Hewitt contracted chicken pox.

Despite her frustration at again being unable to complete the tournament at the Burswood Dome, Molik gained plenty of confidence after three straight wins in the annual competition.

The Olympic bronze medalist defeated Slovak Daniela Hantuchova, Dutch teenager Michaella Krajicek and American Meghann Shaughnessy without conceding a set.

Molik believes it has been the perfect preparation for the year's first grand slam.

"It's great to play three matches and come up with three wins," she said.

"The most important thing is that I played a lot of sets this week, which is how much tennis you want going into a busy Australian summer.

"I feel like I'm hitting the ball great, I just have to keep it up for a few more weeks."

Philippoussis is in doubt for the Australian Open after tearing his groin in two places during Wednesday's loss to Dutch journeyman Peter Wessels.
