BILLY VUNIPOLA is fit to start for England in their mammoth quarter-final against Australia.
The battering ram No 8 was able to train fully ahead of boss Eddie Jones naming his team to face the Wallabies on Wednesday.

Vunipola injured his left ankle against Argentina but is set to take his place against the Aussies on Saturday in an unchanged starting XV.
Replacement Jack Nowell will not feature after tweaking his hamstring in the Pumas game.
Meanwhile Maro Itoje is finally ready to live up to boss Jones’ demand for battle-scarred stars.
England boss Jones questioned Itoje’s lack of war wounds in his early international days — and turned him into one of the baddest and meanest forwards on the planet.
Saracens lock Itoje has never lost to the Aussies and wants to inflict more pain in Saturday’s World Cup quarter-final.
Asked whether he thought he now had an edge, Itoje said: “I hope so.
“I hope I don’t have too many battle scars, though. I’d like to leave rugby blemish free!
“I don’t know how realistic a goal that is but I definitely don’t want to end up looking like Steve Borthwick!
“The greater the risk the greater the reward. I’m really excited for this weekend.
“We want to play well. But without a doubt, we’re looking to beat them.”
