A late Billy Mehmet header saw Perth Glory gain some measure of revenge for last season's A-League Grand Final defeat to Brisbane Roar with a 1-0 win at Paterson's Stadium.
The late substitute was the difference as he headed home a Scott Jamieson cross in the 89th minute.
Adelaide United began their A-League campaign with a 2-0 victory over Newcastle Jets at Hunter Stadium. Dario Vidosic gave the visitors a second-minute lead before home goalkeeper Mark Birighitti saw red early in the second half.
Adelaide made the points safe in the 75th minute when Iain Ramsay slotted home at the back post after a great piece of work from Vidosic.
