Uni suffered their first loss at home this season following a frustrating 2-1 result against Rockingham City.
It was certainly a game of two halves, with Rockingham racing to a 2-0 nil lead in the opening half an hour through James Harmer and Mitch Morrin, which both came on the rebound following stunning saves from promoted keeper Alex Preece.
Tristan Taylor gave the hosts hope and momentum leading into the second stanza on the the stroke of half-time with his persistence paying off with a sliding finish in off the post.
The second-half saw UWA dictate play with wave after wave of attack, but the visitors remained resolute at the back and preventing clear-cut chances.
Uni's dominance was almost rewarded with a point late on, with experienced defender Robbie Black unlucky to not have hit the back of the net from a one-one-on situation and then from a corner just moments later.
But it just wasn't to be for Michael Janssen's men as they fell to a 2-1 defeat at The Mac.
The 18's continued their inspiring form with their third 3-0 triumph in as many weeks, as the reserved played out another entertaining 3-3 draw in front of the home faithful.
UWA enjoy a week off with the bye round this week, but will be back in action on the 11th of May when they travel to take on newly promoted Gwelup Croatia.
