"This group of players found momentum during the World Cup," he said.
"We've been through the positive changes and had momentum at the World Cup but want to prove it wasn't just a couple of one off games.
"We're playing one of the best teams in the southern hemisphere who we lost to in the World Cup.
"It's Wales versus Australia and it's a huge game.
"Against Australia it's about keeping the ball, being accurate, having composure and patience and being physical.
"That physicality starts up front at the set-piece. We have to ask questions there before we want to play rugby."
