United rested several of their big-name recruits for the match, including marquee man Jason Culina but still had too much for their opponents.

Barisic opened the scoring on 20 minutes as he headed in a cross from Adama Traore.

Barisic netted his second when he followed up to pounce - Daniel Piorkowski's initial strike having been parried by the Byron Bay keeper.

The home side pulled one back before United restored their two-goal margin soon after courtesy Piorkowski.  They added another one through trialist Greg Thomas to make it 4-1 before Barisic completed his hat-trick in the dying minutes.

United continue their build up this week with two more warm up games. Rochedale Rovers are the opposition onTuesday, followed by a clash at Tweed Valley on Thursday. Both games will kick off at 7pm.

Gold Coast then entertain Central Coast Mariners on Saturday.
