Australia make four changes ahead of second England Test in Melbourne

Australia have brought in two new props to try to strengthen their scrum ahead of Saturday's second Test against England in Melbourne.

James Slipper and Sekope Kepu will be in the squad in place of Greg Holmes and Scott Sio, with the latter not even making the bench.

Wallabies head coach Michael Cheika has made a total of four changes, with Sean McMahon replacing the injured David Pocock in the back row, and Sam Carter coming in for fellow absentee Rob Simmons in the second row.

The backline is unchanged, however, with Cheika opting to keep Samu Kerevi in a midfield combination with Tevita Kuridrani at the expense of Christian Leali'ifano.
