Sydney FC destroyed Western Sydney Wanderers 4-0 in front of a record A-League crowd of 61,880 at ANZ Stadium to get their season off to a flying start.
Graham Arnold's men opened the scoring early in the second half through Filip Holosko and Holosko was the creator for Bobo to double the advantage four minutes later.
Wanderers' hopes of getting back into the game were dealt a major blow when Aritz Borda received his marching orders with eight minutes left and the visitors made the most of their man advantage as Brandon O'Neill and Alex Brosque poured more salt in the home side's wounds in the closing stages.
Central Coast Mariners pulled off a stunning comeback against Perth Glory to salvage a 3-3 draw in their season opener.
Adam Taggart scored for Perth after just three minutes, before adding a second in the 27th minute to hand Glory a comfortable lead, with Diego Castro making matters even worse for the visitors eight minutes later.
Roy O'Donovan pulled one back in the 56th minute to help his side back into the game and Blake Powell made it 3-2 in the 84th minute, before O'Donovan completed his side's remarkable comeback from the spot two minutes later.
Melbourne City recorded a 1-0 away win over Wellington Phoenix, despite a second-half red card for goalkeeper Thomas Sorensen.
Anthony Caceres did well to get to Bruce Kamau's cross, dribble around Glen Moss and coolly slot home for the only goal of the game after 31 minutes.
Sorensen was dismissed on the hour mark for handling outside his area after Roy Krishna had intercepted a poor back pass from Josh Rose, but the hosts could not find an equaliser.
