Sio is restored at loosehead prop, with James Slipper dropping down to the bench for the climax to England 2015 at Twickenham.

Australia have one survivor from their last appearance in a World Cup final 12 years ago in centre Matt Giteau, who has been passed fit after suffering a groin injury in the 29-15 semi-final victory over Argentina.

Number eight David Pocock and full-back Israel Folau have shown no adverse affects from the respective calf and ankle complaints that forced them to miss the clash with Scotland in the last eight.

“This week we’ve had a strong focus on improving certain areas in our game where we feel we haven’t been at our best in previous matches,” head coach Michael Cheika said.

“We still have lots of scope to improve and we’ll work on that before this next match against New Zealand.

“Our lads are learning to cherish each opportunity they have in the gold jersey and this week we have that opportunity again. We’ll be doing our best to make Australia proud of its rugby team.”
