And the winner came in the most dramatic style off a deflection of Joe Plumb's stick from a hit outside the circle which caught the Wests' keeper Matt Perry completely off guard.

It was heartbreaking for Wests captain Jimmy Liddell whose team had led 2-0 into the second half when University suddenly came back to level scores.

Liddell said the turning point came when Wests' Josh Gregory was handed a yellow card for a foul after leading 2-0 and the team lost it after this.

Elliott Ashby put Wests ahead in the first half and added the second 10 minutes into the second half but the Students broke through in the 50th minute when Landon Morley scored from a penalty corner.

With Kookaburrra Flynn Ogilvie back on the field from his training base in Perth, he kept his team on the offensive and 10 minutes later relayed the ball to brother Heath to level scores 2-2.

When all thought the game was leading into extra time, the game took a dramatic turn with the  winner in the final seconds of the game.

University coach Heath Ogilvie said it was a good win for the Students with Wests playing well and sticking to a game plan.

"We just had faith in what we try to do and just have good self belief in the team," Ogilvie added.

Injured Kookaburra Kieren Govers also made a return to hockey to score two goals in Albion Park's 4-0 win over the Falcons in the minor semi-final.

Brady Anderson and Rhys Gray scored the other goals for the Park who now face Wests in the minor final on Sunday at 3pm.
