The Australian Lacrosse League (ALL) was an elite-level men's lacrosse competition that ran from 2004 to 2007 with the aim of boosting the profile and participation of the sport in Australia. The ALL replaced the Australian Senior Lacrosse Championships, which was held annually during a week-long carnival. Due to the unpopularity among some groups toward the format of the competition, from 2008 the national championship is again been contested as a carnival at a single venue.
Teams played each other twice, with double-headers (a Saturday and Sunday game) played over three weekends. Each state hosted one double-header and travelled for the other. The two teams with the best win/loss record over the round-robin tournament progressed to the final, played on the weekend following the last round-robin match.
