Wales head coach Ioan Cunningham has made four personnel changes and two positional switches for the pool-stage finale against Australia on Saturday (2.15am UK kick-off) with a guaranteed spot in the quarter-finals at stake.
The losing side in the fixture could yet progress to the knockouts as one of the two best third-placed teams across the groups, but Wales will not want to leave it to chance.
Following on from the 56-12 defeat to reigning champions New Zealand last weekend, Cunningham has made a number of changes to his starting side.
