Two tries to Will Genia has helped the Wallabies string back-to-back wins for the first time this year after a 36-20 victory over an ineffective Argentina in Perth on Saturday.

The Wallabies were electrifying out of the blocks, running riot on the Pumas with three tries in the opening 13 minutes before a try and some outstanding service from man-of-the-match Genia propelled Australia to their second win of the year.

Five-eighth Quade Cooper's composure and timing was a feature of his third consecutive game at No.10 as he directly set up Dane Haylett-Petty and then Michael Hooper in the 64th minute to all but put the result beyond doubt, with two pinpoint inside passes.

The victory lifts Australia to second on the Rugby Championship standings and will be a major confidence booster with trips to Pretoria, London and Auckland to come before a Spring Tour.
