Forward Greg Eastwood is the only change to the 19-man squad named to face the home nation, replacing Canberra back rower Joseph Tapine.
"It's no secret this game is going to be won up front," says Kidwell. "Both teams have strong forward packs and we need our middle men to lead the way."
Kidwell and his coaching staff have put the full squad through their paces since arriving in England last Thursday.
"I'm really happy with how the boys have trained. We understand the challenge that's ahead of us and we need to be at our best," he says.
