Serena Williams defeated Lindsay Davenport in the final, 2–6, 6–3, 6–0 to win the women's singles tennis title at the 2005 Australian Open.[1] It was her second Australian Open singles title[2] and her seventh major singles title overall. Williams saved three match points en route to the title, in the semifinals against Maria Sharapova.
Justine Henin-Hardenne was the reigning champion, but did not compete this year due to a knee injury.
This event marked the first major appearances for future world No. 1 and major champion Ana Ivanovic and two-time major champion Li Na. Both reached the third round before losing to Amélie Mauresmo and Sharapova, respectively.
