The 2007/08 season was the third season of the A-League in football . Champions were the Newcastle United Jets for the first time , who beat the regular season champions, the Central Coast Mariners , 1-0 in the final . Last year's finalists Melbourne Victory and Adelaide United both missed the play-off round. With Wellington Phoenix , a new team took part in the game for the first time since the league was founded. Phoenix replaced the New Zealand Knights , whose license was revoked in the previous season.
Before the start of the A-League season, the mandatory pre-season cup was held.
Pre-Season Challenge Cup
The Pre-Season Challenge Cup 2007 took place in July and August as a run-up to the main season. The eight A-League teams were initially divided into two preliminary round groups of four teams each and played in a simple league round. In the league round there were not only normal points but also bonus points for goals scored. Two goals scored one point, three goals earned two points and three bonus points were awarded for four or more goals.
The two group leaders in each group advanced to the semi-finals and played the winner in a knockout process. The table third and fourth played placement games.
Some of the games were played in Australian cities without an A-League team to promote the league there.
In the final, defending champions Adelaide United beat Perth Glory 2-1.
