Australia survived a late scare to defeat a committed Argentina 32-25 in the Rugby Championship in Gold Coast on Saturday.
Having led 29-13 with 20 minutes remaining thanks in part to a double from captain and flanker Michael Hooper and a Peter Betham try, the Wallabies appeared on course for a comfortable victory.
But Argentina refused to lie down and scored two tries in seven minutes to cut the gap to four points and set up a tense finish at the Cbus Super Stadium.
However, man-of-the-match Bernard Foley converted his fifth penalty to open up a seven-point advantage as Ewen McKenzie's men stood firm to move level with South Africa on 10 points, six behind leaders New Zealand with a triumph that was somewhat soured by an apparent serious ankle injury to hooker Tatafu Polota-Nau.
Argentina, whose flanker Juan Manuel Leguizamon did not complete the game due to an ankle problem, collected their third bonus point of the season but remain bottom on three points.
Hooper opened the scoring in the second minute, bursting on to a pass from fly-half Foley, but Argentina quickly responded through winger Manuel Montero to take a 7-5 lead.
Talisman Foley turned the tide in Australia's favour, though, with three first-half penalties to put McKenzie's side 14-7 to the good at the interval.
A second from Hooper, a further Foley three-pointer and Betham's first try in Australia colours appeared to have put the game beyond doubt.
Yet Argentina rallied with a converted try from Marcelo Bosch, although fly-half Nicolas Sanchez could not add the extras after seeing his grubber kick pounced on by Joaquin Tuculet.
Foley then established some breathing room for Australia and the seven-point gap proved too much for Argentina to bridge, their best chance to level coming to nothing as Sanchez opted not to pass the ball to unmarked winger Juan Imhoff in the 79th minute.
