Andre Agassi defeated Rainer Schüttler in the final, 6–2, 6–2, 6–1 to win the men's singles tennis title at the 2003 Australian Open. It was his fourth Australian Open title and his eighth and last major title overall.[1] [2] With the win, Agassi claimed his 21st consecutive match win at the Australian Open, as he won the title in 2000 and 2001 (he did not play in the 2002 event due to injury).
Thomas Johansson was the reigning champion, but did not participate due to injury.
