University flyhalf Alan Kingsley was named man of the match as he guided his side brilliantly around the field and kicked all of his side's points.
"I'm delighted," said Uni Coach Steve McFarland, "the last time the club won was 1972 so it's been a long time between drinks and we're all absolutely delighted with this result.
"There were great performances across the park.
"We were very strong on defence and we were far better at the breakdown than we were against Nedlands a couple of weeks ago.
"Alan (Kingsley) in particular was outstanding for us today.
"He was cool, calm and kicked confidently under great pressure.
"In a grand final things are always different but he just looked right at home out there."
It was Kingsley's boot that saw his side through to the Premier Grade Grand Final with a 79th minute penalty that gave his side a 19-18 win over Cottesloe the previous week.
Kings' inspirational kicking has made him the club's highest points scorer with a tally of 163 this season.
Alan Kingsley was not the only Munster representation on the UWA team that won the KWIK Premier Grade Grand Final, four former Shannon players Andrew Finn, Fionn McLoughlin, Trevor Downes and Cian O'Connor also play with the side. No doubt the boys will still be celebrating what is an historic win for the University side.
