Where to Watch
Kick-off is at 2:30pm and is live on Sky Sports 2HD on Saturday 29 November.
Live commentary is available on BBC Radio Five Live Sports Extra. Highlights are on BBC Three at 7pm on Saturday 29 November and repeated at 12:30pm on Sunday 30 November.
A match which has been overshadowed by the death of Australian cricketer Phil Hughes has huge ramifications ahead of next year's World Cup.
Wallabies coach Michael Cheika has admitted to shedding a tear over the passing of Hughes, for whom a minute's applause will be held before kick-off at Twickenham just days after he died after being hit by a cricket ball at the Sydney Cricket Ground.
After the tribute, England and Australia go to war just 11 months before the pair go head-to-head to their final pool match which could work as a straight shoot-out for a place in the quarter-finals.
England have endured a difficult autumn, losing to New Zealand and South Africa and edging to victory over Samoa while concerns remain over their midfield which endures another change for the visit of Australia.
Billy Twelvetrees has replaced Owen Farrell in another change to the centre pairing, while George Ford - fresh from an impressive performance on his first start for England last weekend - begins at fly half.
Despite suffering successive losses to France and Ireland, Australia's brand of enterprising rugby could expose a weak England this weekend and provide the worst possible preparation for the World Cup on home shores.
Australia's final scheduled test before their opening match against Fiji sees Israel Folau start at full-back while Adam Ashley-Cooper and Matt Toomua are in midfield.

What the coaches say
Stuart Lancaster: "Execution under pressure is what we need to improve. We need to get all our critical choices right and that is what our decision-makers have been told if we are to come away with a win. We gave away unnecessary penalties and better discipline has been the message we have given the players.
"The result will be a mood shaper going into the Six Nations and if we finish the autumn with a win it will be a big mood shaper for me. As coach, what weighs on my mind is the chance for the supporters to see success and their backing has been brilliant."
Michael Cheika: "Belief that we can be successful. You've got to believe what you do and don't react to everything. Eventually people respect that. I believe in the team we have for the team, that gives me confidence. I've been where people are throwing eggs before, you've just got to hold your nerve and eventually that comes out.
"I have never been scared to make a few different decisions around selection, I am happy to give these young guys a go and they're going to be the future as well."
