In 2009 the tournament was expanded to feature the premiers from the Western Australian league competitions, plus a wildcard entry for the fourth spot, given in the first instance to the previous year's national champion if they did not win their state league, or otherwise the non premiership team with the best home and away record for their league. With four teams in each of the men's and women's championships, semi finals are played to determine who plays in the championship final the following day.
