Cane's tackling was superb throughout but in a game of big hits, undoubtedly the one put in by 135 kilo prop Ben Tameifuna on Hooper was the standout.
The Waratahs had won all seven games they have led at halftime and that trend continued, although it looked as if the Chiefs may break that when they took the lead 19-17 with 15 minutes to play after the second try to replacement Bundee Aki.
But late tries to captain Dave Dennis and Bernard Foley put paid to those hopes.
Waratahs 33 (Israel Folau, Dave Dennis, Bernard Foley tries; Foley 3 cons, 3 pens; Kurtley Beale pen) Chiefs 17 (Bundee Aki 2 tries; Aaron Cruden 2 cons, pen)
