Wallabies coach Michael Cheika has overhauled his team, making seven changes to the starting line-up to face Argentina with Michael Hooper and Quade Cooper among the casualties.

Despite last week’s last-gasp win over South Africa to open Australia’s Rugby Championship campaign, Cheika has put the broom through the side as he continues to search for his best World Cup line-up.

David Pocock has won this round’s battle for the openside flanker role, relegating fellow former captain Hooper to the bench.

Cheika resisted the temptation to start two fetchers – Pocock and Hooper – together in his backrow and recalled Ben McCalman at No.8 in place of Scott Higginbotham, who drops out of the match squad.

In the other change to the starting pack, renowned scrummager Greg Holmes replaces prop Sekope Kepu, who drops to the bench.

The backline has also been reshuffled, with a new halves combination in Nick Phipps and Bernard Foley.

Phipps takes over from the injured Will Genia while five-eighth Foley has relegated Cooper to the bench.

Joe Tomane is the injured Rob Horne’s wing replacement while Matt Toomua will start at inside centre in place of Matt Giteau who is also out injured.

New faces on the bench include lock Dean Mumm, halfback Nic White and utility back Kurtley Beale, who returns from injury to bump Drew Mitchell out of the squad.

Australia lost to Argentina in Mendoza last year 21-17.
