Australia fed off Wales' errors and ran in four tries in a clinical 29-21 victory in Cardiff on Sunday, extending its winning streak over the Welsh to 13 test matches.
The Wallabies have played seven tests since their opponent's last, and their match sharpness told in the first half, when Wales paid the price for failing to clear its lines at restarts and its ambitious, high-tempo game plan.
Hooker Tatafu Polota-Nau rolled over at the back of a maul, lock Adam Coleman crashed over from close range, and flanker Michael Hooper squirmed over the line at an overlap to help Australia to 22-13 at halftime.
Wales had the better of the second half under the Principality Stadium roof, but was hit by a sucker-punch when fullback Kurtley Beale stole the ball from Steff Evans and raced 60 meters to ground between the posts in the 63rd minute.
The Australians stretched their unbeaten run to seven tests - including a victory over world champion New Zealand last month - and haven't lost to Wales since 2008, a run that includes eight straight wins in Cardiff.
