The Western Force's wait for a first Super Rugby AU victory goes on after they were beaten 28-8 by the Waratahs on Friday.

Michael Hooper celebrated his 150th Super Rugby game with a victory at Cbus Super Stadium, as the Waratahs outscored the bottom-of-the-table Force by three tries to one.

The Force led twice in the first half courtesy of a Brynard Stander try and a penalty from Ian Prior, but Alex Newsome's try and 11 points from the boot of Will Harrison gave the Waratahs a 16-8 advantage at the break.

There was no way back for the Force after the interval, Jack Maddocks' intercept try giving Rob Penney's side breathing space and Harry Johnson-Holmes crashing over in the closing stages on the Gold Coast.

The Waratahs, who welcomed Rob Simmons back from injury, are up to second after securing back-to-back Super Rugby victories for the first time since March 2019.
