#5 Serena Williams
The last and final player on this list is undoubtedly the greatest female player of this century, Serena Williams. Williams has won 5 titles at Melbourne Park, which is the most by any player in the Open Era. The American broke through in 2003, winning her first title by beating older sister Venus in the final, a win which also made her the holder of all four slams at the same time.
Her legacy at the Australian Open was further enhanced by victories in 2005, 2009 and 2010, however, it is possibly the 2007 triumph for which she will be remembered the most. Entering the tournament as an unseeded player, and ranked an unbelievably low No.95 at the start of the year, Williams slowly made her way though the rounds, before annihilating Maria Sharapova in the final, losing just three games en route to a resounding victory.
And the best part? She is by no means done and is one of the favourites at Australian Open 2015
