Wales coach Warren Gatland has made four changes for Saturday's must-win Test against Australia at the Millennium Stadium.
All the switches have come in the forwards, three of them enforced, as Wales attempt to sign off a wretched autumn series with a victory.
Gethin Jenkins starts at loosehead in place of Bath's Paul James, who is unavailable as the Wallabies game falls outside of the IRB's autumn Test window, while Scott Andrews comes in at tighthead for the injured Aaron Jarvis.
Lock Ian Evans takes over from Bradley Davies, who was left with concussion after being struck by Andrew Hore in the first minute of Wales' defeat to New Zealand last weekend.
The one form change comes in the back row, where Aaron Shingler replaces former captain Ryan Jones, who drops to the bench alongside uncapped prop Samson Lee.
An Australia victory would condemn Wales to the third tier of countries for next Monday's draw for the 2015 World Cup.
Gatland said: "We need to pick up again from where we left off in the second half last week.
"We managed to retain 73 per cent possession after the break against the All Blacks and win the territory battle, and we need to put Australia under similar pressure from the outset.
"We've played them regularly over the last couple of years and have come close to winning on a number of occasions, but have not quite been able to get ourselves over the chalk of the finish line.
"Both sides have had injuries to cope with, but there is every reason for optimism."
Wales: Halfpenny, Cuthbert, Davies, Roberts, L Williams, Priestland, Phillips; Jenkins, Rees, Andrews, Evans, Charteris, Shingler, Warburton (captain), Faletau.
Replacements: Owens, Bevington, Lee, R Jones, Tipuric, Knoyle, Biggar, S Williams.
