Roger Federer won his second Australian Open title, defeating Marcos Baghdatis in the final in four sets.

Amélie Mauresmo won her first Australian Open title, defeating 2004 champion Justine Henin in the final; Henin-Hardenne was forced to retire at 1–6, 0–2 down due to a stomach virus.

It began Henin-Hardenne's run of reaching the final of all four Grand Slam events, winning the French Open.

Several leading men's players declined to attend the Open due to injury, including Andre Agassi, Rafael Nadal and defending champion Marat Safin.

Lindsay Davenport and Serena Williams were among those who welcomed her return to the circuit as a positive step forward for women's tennis.
