The Waratahs bagged a full house of Super Rugby points in Perth after sweeping aside the Western Force 31-3 on Saturday.
The hosts' are yet to post a win at home in 2011 as they fell to their fifth defeat, while their Aussie rivals made it back-to-back victories thanks to a brace of tries from Drew Mitchell.
Wallabies scrum-half Luke Burgess starred in the dominating display by setting up the Waratahs' first three tries, while fly-half Kurtley Beale contributed 11 points from the boot, including converting his own second-half try.
James O'Connor booted over the only points for the Force.
The 'Tahs never gave an inch but the Force's wave of errors didn't help their cause either while their ill-discipline was less to be desired. Their only saving grace was Waratahs fly-half Kurtley Beale's poor showing with the boot, converting only one of the three early shots at goals.
O'Connor replied to level the scores after 19 minutes but ten minutes later Burgess' set up the game's first try when he made a break before feeding Tom Carter for the score.
Burges was in the thick of things again seven minutes later when he put Former Force star Mitchell through for a brilliant try.
Beale slotted his second conversion to make it 17-3 at half-time.
Burgess continued to torment Force with his creativity and on 52 minutes he dashed any hopes they had of a fightback when he sent Beale in under the posts.
The bonus point came in the 66th minute, when Mitchell sliced through Force's poor defence to claim his fifth try of the season.
The win completed a clean sweep for the Waratahs over the other Australian teams this season.
