Matt Renshaw, Peter Handscomb and Nic Maddinson all wore the baggy green for the first time during Australia's seven wicket win over South Africa in the third Test, and each player enjoyed differing performances.
Matt Renshaw (10, 34*)
While his match run tally of 44 may not warrant a lot of praise, the way Renshaw batted in both innings showed poise beyond his years.
At just 20 years of age Renshaw was thrown into the deep end, as he as usual first-drop Usman Khawaja had to face 12 overs under lights after South Africa declared.
Renshaw remained at the crease overnight, and did his job in the first innings.
He carried his bat through the second innings as the hosts lost three wickets on the way to chasing down 127, and Renshaw's 34 from 137 was definitely the highlight of Australia's second stint with the bat.
The youngster remained calm throughout the entire Test and stayed patient, and should definitely keep his spot for the first Test against Pakistan.
Peter Handscomb (54, 1*)
The Victorian lit up Australia's first innings scoring a debut half-century in an assured performance.
Like Renshaw, Handscomb was quite confident with the bat and didn't look flustered, although he wouldn't have been too happy after being clean bowled by Kyle Abbott.
Handscomb also impressed in the field, taking a screamer in the gully to send Proteas captain Faf du Plessis packing for just 12 runs, which was a huge wicket for the hosts.
The debutant managed to hit the winnings run on a night he'll never forget, and his fate should be sealed for Pakistan too.
Nic Maddinson (0, dnb)
While the other two shouldn't have problems about regaining their spot for the opening Test against Pakistan in Brisbane, Maddinson has a little bit more to worry about.
The New South Welshman was bowled by Kagiso Rabada with a beautiful delivery, and failed to get off the mark during his 12-ball duck in the first innings.
Maddinson wasn't called on again as Australia cruised to victory, and a no-run Test is never a good sign.
It would be a harsh call to drop Maddinson given he was apart of the team's first victory of the summer, but his position is easily the most vulnerable of the three newbies.
