Stewart Kean's injury-time strike sealed a win for Queens in front of the Live TV cameras to stall the Saints charge for promotion after a late fight back by the Perth side
Queens took the lead in the 11th minute through Stephen Dobbie's low shot and the former Saints man doubled his tally in the second half with a 55th stunner.
Just as it looked bleak for Saints, Derek Holmes pulled one back with a free header in the box.
A Chris Millar shot was then deflected in by Jim Thomson for a stunning equaliser, until Kean stole the points with his late winner.
Queens had to fight all the way for the points especially in the second half but it was a great team effort with Dobbie's goals again crucial.
