It led to the biggest loss to NSW in 19 seasons of Super Rugby and their lowest score at Suncorp Stadium.
But, otherwise, Queensland's competitiveness rattled the Waratahs in a searching warm-up for their home semi-final on July 26.
Captain Dave Dennis' lineout calling was sorely missed as they gave up five throws in the first half and several more after the break.
The Reds boast one of the best defensive lineouts in the competition but coach Michael Cheika will have plenty to do to fix the problems in their week off.
"It is (a chink in the armour) but that's the beauty of it - we have two weeks to take care of it," skipper Michael Hooper said.
After a frenzied opening five minutes, where they took a 3-0 lead and pulled off a couple of big hits and lineout steals, it was a nightmarish start for the Reds.
Playmaker Ben Lucas injured his knee and left the field. Then centre Ben Tapuai, one of the very few first-choice players in the starting backline, was concussed as he attempted to tackle Cam Crawford in the lead-up to Beale's 16th-minute try.
Beale had just gathered his breath from stepping between two forwards to send former Reds fullback Jono Lance over.
But the rest of the first half the Waratahs were forced to soak up Queensland pressure as the Reds' set-piece dominated, particularly with Sekope Kepu sin-binned for punching fired-up ex-Waratah Beau Robinson.
It was Beale's second try, starting it with a chip for Adam Ashley-Cooper inside his half, which sealed the result in 55th minute while Nick Phipps put the icing on the cake with a late try in the corner.
