Wales have reverted to the starting team that beat Fiji for their World Cup clash with Australia.
Dewi Lake is left out of the squad having led the side against Portugal, with Ryan Elias preferred at hooker.
Prop Henry Thomas is set to make his tournament debut from the bench.
Victory for Wales would guarantee a place in the quarter-finals and leave Australia on the brink of exiting a World Cup at the pool stage for the first time in their history.
Jac Morgan once again captains the side having played a full 80 minutes against Fiji and being called in as a last minute replacement for Tommy Reffell against Portugal last weekend.
He is joined in the back row by Aaron Wainwright and Taulupe Faletau at number eight.
Will Rowlands and Adam Beard resume their partnership in the second row, with Gareth Thomas, Elias and Tomas Francis reinstated in the front row.
Liam Williams starts at full-back, with Louis Rees-Zammit and Josh Adams on the wings, despite stiff competition from Rio Dyer who impressed against Portugal and is named among the replacements.
George North partners Nick Tompkins in the midfield, with Dan Biggar and Gareth Davies as half-backs.
More to follow.
