Wales centre Jamie Roberts hopes that the prize of finishing top of Pool A will bring out the best of his side when they face Australia.
The Wallabies haven't lost to Warren Gatland's side going all the way back to 2008, although several Welsh players were involved in the British and Irish Lions' series win over Australia in 2013.
As for Wales, their last five games to the Wallabies have been lost by a margin of five points or less.
“Their backline has changed significantly. A few of the boys have experience of beating Australia. Looking back over the last seven years it’s the same old story. Over the last 10 minutes, they have killed us on many occasions," said Roberts.
"I hope that what is on the line on Saturday (ending first or second in Pool A) will bring out the best in us.”
Roberts watched the game in Richmond and admitted to feeling nervous throughout, and even a little sympathy towards England as they were knocked out of the tournament.
“I was shaking for 80 minutes. It was like playing a game, though not expending as much energy. There was a decent set-up at Rosslyn Park (Richmond) where I was watching a few of my mates playing. I sat on the sofa in front of the big screen and didn’t move.
“It was a bit awkward being surrounded by a load of English. When it got to 20-13, I’m sure the whole of Wales was panicking a bit.
“It’s a brutal pool. There were always going to be three teams who missed out. It’s the nature of the beast and what makes the World Cup exciting.
"We know the questions being asked of England. It’s about fine margins and those questions could have been asked about us if we had lost to England.
"I did feel a touch of sympathy.”
