Michael Cheika has made a number of changes to his Wallabies side ahead of Saturday’s must win clash against England at AAMI Park in Melbourne.

Rebels backrower Sean McMahon will start at No.8 in front of his home crowd, replacing the injured David Pocock.

Sekope Kepu and James Slipper join captain Stephen Moore in a new-look front row while Sam Carter will pull on the gold jersey for the first time since Australia’s 47-10 win over the United States in Chicago last year.

Cheika has stuck with the Fijian centre duo of Samu Kerevi and Tevita Kuridrani for the second Test, with Christian Lealiifano on an extended bench.

In fact, the Wallabies coach has left the backline unchanged from that which ran out in the opening Test in Brisbane last weekend.

Cheika has named an extended bench, including Liam Gill, Luke Morahan, Toby Smith, Wycliff Palu and Ben McCalman from outside last week’s 23, with the final reserves make up to be confirmed on Friday.

“Based on last weekend’s performance, we decided that we wanted some new combinations for Saturday’s game,” he said.

“Sean never takes a backwards step while James and Sekope add plenty of Test match experience.”

Morahan is one that could add to his Test debut, with Cheika opting for an extra back on the bench, unlike the opening Test’s six-two split.

“Obviously with his (Morahan’s) selection, we’re looking at a five-three split on the bench as opposed to the six forwards we had last weekend,” Cheika said.
