File Pic[/caption] Internet Desk: A new look Australian team under Steve Smith will look for redemption as they take on South Africa in a Day Night test in Adelaide starting Thursday.

The hosts will make five changes to the squad that played in the second test at Hobart. Matt Renshaw, Peter Handscomb and Nic Maddinson will be handed over the baggy green caps.

It will be interesting to take a quick glance at the average age of Steve Smith’s side.

Less than 18 months ago in Cardiff, for the first Test of the Ashes, Australia fielded a team in which more than half were aged above 30 and the average was 30.9.

On Thursday that figure will be 26.5. Only David Warner is beyond his 20s.

"Davey Warner keeps telling me he's the only one in the 30s now, he feels like an old man," Smith said.

"I think it's a great opportunity for me to stamp my authority on this team as the leader. I have talked a lot to the guys over the last couple of days about growth and trying to grow and learn as a team.

"I know that growth doesn't happen overnight, so it could take some time, but I am confident that with the guys we have here that we can start turning our results around straight away and start playing the way we want to play."

South Africa will look to have a first series whitewash, a rare feat achieved by any visiting team Down Under. Potent pace bowling duo of Kagiso Rabada and Vernon Philander will be raring to go with the pink ball in hand.

"To see the changes now, that brings pleasure to see what we're doing. What we're doing is creating something in the Australian team they feel they need to change," said South Africa's captain Faf du Plessis.

"If I was sitting in that team, a lot of changes mean you're trying to change everything in your team. I'd rather be sitting on my side."

Australian captain Steve Smith backed his new youngsters in the side and emphasized the new crop must be given time.

"You want guys to come in and perform. But this is a great opportunity to get a bit of continuity ... try to make them as comfortable as we can," he said.

"I know that when you are comfortable and relaxed you play your best cricket. I want to try to get that sort of feel in the group."

Pacer Jackson Bird will replace Chadd Sayers in the bowling line for the home team.

Smith reported that the newcomers had already delivered a shift in attitude and energy to the team but he knows that for that to translate into results they must address the primary culprit for five successive Test defeats – Australia's batting deficiencies.

"It's about trying to stay in the moment and identify those [difficult] periods and get through those periods and when you do that things get easier," he said.

"[There has been a] lot of talk about having some fight and grit and just trying to stand up and get through the difficult times."
