It is the four-way Manuka Oval batting shoot-out that will have a major say in the makeup of a revamped Australian Test team.
Joe Burns, Cameron Bancroft, Usman Khawaja and Adam Voges all have the opportunity to push their claims when they line up for the Prime Minister's XI against New Zealand under lights on Friday.
The quartet can show they can handle a potent Black Caps bowling attack ahead of the first Test at the Gabba on   November 5. 
The retirements of Michael Clarke, Shane Watson and Chris Rogers from the Test team after the Ashes has opened the door for the next generation to step forward.
Shaun and Mitchell Marsh will also be involved in the two-day CA XI fixture starting on Saturday.
Test captain Steve Smith and opener David Warner are the only certainties in the Australian top six for the first Test.
Burns is a chance to partner Warner at the top of the innings - like he did in the recent one-day series in England - but he can also play in the middle order.
The 26-year-old batted at No.6 for Australia when he made his Test debut against India on Boxing Day last year at the MCG.
He missed out in that match, but made half centuries in both innings of the fourth Test at the SCG in   January.
Despite that, Burns was overlooked for the tour of the West Indies and the Ashes.
"It was a great experience, it was a very surreal feeling," Burns said.
"Once you get out on to the middle, it feels very familiar.
"I guess you are always disappointed if you miss out on selection on any team.
"The silver lining to it was to have some sort of success and then miss out, gives you confidence that you don't have to go away and change too much.
"You just have to keep doing what you're doing and putting the runs on the board and the opportunities will come."
Burns made his ODI debut against Ireland and retained his place for the five-game series with England.
He was selected in Australia's 15-man squad to tour Bangladesh in   September, which was cancelled because of security concerns.
Burns sees the PM's XI game as a fantastic opportunity to get a look at the outstanding New Zealand bowling attack of Tim Southee and Trent Boult.
"It's the first chance for a lot of the guys to face the New Zealand bowlers," Burns said.
"Just to face them and get some sort of experience for that first Test at the Gabba.
"They're good new ball bowlers and you need to be on the ball from ball one.
"The more you've seen of them, the better prepared you are."
All of the four players, with the exception of Bancroft, have had a taste of Test cricket before.
The 22-year-old burst on to the scene with Western Australia in the Sheffield Shield and performed strongly for Australia A this year.
WA fast bowler Jason Behrendorff said Bancroft brought plenty to the table.
"Bangers is one of the hardest working cricketers you'll meet," Behrendorff said.
"He is one of those blokes that if you told him you needed to jump off a bridge to get better at his cricket, he would.
"He'll do anything to improve his cricket.
"He's done great things, especially in the last couple of years.
"He grinds at the top of the order and makes sure we get off to a great start.
"For the guys in the know, it was no surprise he got picked, his domestic form was outstanding."
