In truth the score perhaps flattered Sydney a little as Adelaide dominated after a tight opening with Dario Vidosic especially impressing.
Adelaide got on the board in the 18th minute as Marcelo Carrusca sent in a cross that found Vidosic in the middle of the box allowing him to head home in to the upper corner of the net.
Just ten minutes later the Reds doubled their lead as Bruce Djite was brought down by Seb Ryall which allowed Vidosic to score his second, from the spot and give Adelaide a commanding lead.
Djite should have made it three in the 39th minute when he got around Ryall but his low strike flew just wide of the goal letting Sydney off the hook but only momentarily as less than a minute later Evan Kostopolous had a shot but was denied by a superb save as Vedran Janjentovic tapped the ball on to the crossbar.
Yairo Yau had what was really Sydney’s only chance of the half in stoppage time as he worked his way behind the Adelaide defense but without support ran out of space, keeping Adelaide safe with a 2-0 half-time lead.
Adelaide continued to dominate after the break and Vidosic should have had his hat-trick just two minutes in but lifted his shot over the bar after Aaron Calver’s poor defensive clearance.
In the 61st minute Adelaide finally did make it three after Janjentovic made a solid save to deny Djite only for Iain Ramsay to follow up and score with a simple tap-in.
The chances kept flowing and Vidosic had another chance to net his hat-trick through a powerful 72nd minute free-kick which came off the bar.
Vidosic’s frustrating night continued late on after he turned Rhyan Grant and then hit a powerful shot which again could only find the woodwork.
Vidosic never would get his hat-trick but Adelaide got their season back on track, while for Sydney it was back to their poor form as they were completely outplayed.
