Despite a spirited performance, uni fell to a 2-0 defeat at the hands of league leaders Gwelup Croatia in Round 17.
The hosts were left to rue their missed opportunities in the first-half, as two late goals from Gwelup condemned UWA to a home loss.
Uni began the contest in fine fettle, with their structure and high pressing forcing the visitors into a number of long-balls out from the back.
Michael Janssen's side almost opened the scoring 15 minutes in, with Bryce Conway's whipped cross to the near post met by a glancing header from Conor Devlin, which flashed narrowly passed the post.
Uni continued to look dangerous down both wings, with Mordecai Junior dribbling his way into the area and firing a shot that seemed to strike the outstretched arm of Gwelup centre-back Cam Yorke, but the shouts for a penalty were waved away as it remained 0-0 at the break.
It remained a tight contest in the second half, with both sides creating plenty of half chances in an open and entertaining contest. Luke Randazzo went closest for uni, with Alex Kretowicz's clever pass carving open a great opportunity for the midfielder, as he surged through the centre of the defence, but his shot dragged agonisingly across the face.
Gwelup eventually broke the deadlock with just over 20 minutes remaining. A defensive error presented a golden chance for the visiting side and they made no mistake from close-range.
It was 2-0 five minutes from time with captain James Sammut securing the result with a volley from outside the area.
UWA rallied until the final whistle, but it just wasn't meant to be on a sunny afternoon at The Mac.
In other results, the Reserves suffered a 2-1 loss, while the 18's drew 1-1, but remained four points clear at the top of the table.
