Australia confirm return of Pat Cummins, spinner Nathan Lyon for third Ashes Test

Michael Neser and Brendan Doggett are the players that miss out from the victory in Brisbane, while the hosts have also opted to retain Travis Head at the top of the order.

Head's role as opener means Usman Khawaja has again been left out, meaning the 39-year-old could potentially have played his final Test match for Australia.

Cummins told reporters: "I think the big thing that's shifted on us is probably Trav opening after that first Test and how good that has looked with the Weathers, so we're pretty happy with that batting line-up.

"It didn't feel like it needed to change in the middle order.So far it's looked like they (Head and Weatherald) have been able to keep the scoreboard ticking over.

"Whatever has been thrown at them, they've had an answer to. It's really set up the platform for our innings.

"I think you've seen people like Marnus (Labuschagne) and Steve (Smith) walk in after that as well and really get on the back of that and start their innings well.

"I don't know if it's scrambled the opposition, but it's certainly kind of got that momentum, kept that scoreboard ticking over and started our innings brilliantly."

The Australia skipper also lauded his team's depth as they are currently 2-0 in the five-match series while he and Josh Hazlewood have not yet played a game.

"Incredible, I think it shows just great depth in the Aussie cricket system at the moment with fast bowlers," Cummins said.

"When I said it's almost worked out perfectly...we're halfway through a series, I've come back on line, you've got Ness and Doggy who are resting from this week, but they've obviously got themselves into the series and are available for the last two games.

"You've seen Jhye Richardson out the back bowling. So it feels like everything's come together and we're not just hanging on to the end of a series like sometimes you are.

"We're actually peaking and hopefully there are heaps of resources available. But the guys who have stepped in have been fantastic and I think it's a huge credit to those guys who have stepped in but also the coaches and Steve managing those guys throughout the day."
