Thomas Johansson could not defend his 2002 title due to an injury which would rule him out for all of 2003. Jennifer Capriati was unsuccessful in her title defence, being defeated in the first round by German Marlene Weingärtner. Andre Agassi won his fourth Australian Open and final Grand Slam title, defeating Rainer Schüttler in a lopsided final.
