Pre-Season Challenge Cup
The Pre-Season Challenge Cup 2008 took place in July and August as a run-up to the main season. The eight A-League teams were divided into two preliminary round groups of four teams each and played in a simple league round. The two group winners advanced to the final and played the winner in one game.
Most of the games were played in Australian cities without an A-League team to promote the league there.
In the final Melbourne Victory prevailed 8-7 on penalties against Wellington Phoenix.
