The Wallabies remain undefeated in the Rugby Championship following a gritty 34-9 bonus-point win over Argentina in Mendoza.

Tries to Joe Tomane, Dean Mumm, Tevita Kuridrani and Adam Ashley-Cooper, and 14-point haul from the boot of Bernard Foley, was enough for the Wallabies to claim consecutive victories in the tournament, although it was largely an undisciplined performance.

The Wallabies, who opened the Rugby Championship with a 24-20 win over South Africa in Brisbane last weekend, gave away 13 penalties and free kicks, while Quade Cooper was handed a yellow card during the second half.

They next face New Zealand in Sydney on August 8 in their final Rugby Championship appearance.
