The Wallabies have scored a wet and wild comeback 20-19 win over Argentina to revive the new-look side's Rugby Championship campaign.
It took a penalty from substitute Ben Donaldson on the buzzer to secure it and snap an eight-game Rugby Championship losing streak.
Australia trailed 10-0 and 16-7 at Estadio Jorge Luis Hirschi in La Plata, just south of Buenos Aires on Sunday (AEST), but found a way in driving rain to improve to 1-2 in the four-team tournament.
