Fresh off 125 not out and two wickets against the Indians in the first tour match, Green on Wednesday said it was hard to know if he was ready for Test cricket.

But what the 22-year-old does know is another big return in a day-night match against India at the SCG starting on Friday can only help his chances of a Test debut this summer.

Green will again feature in the Australia A side for the three-day match, with the vast majority of India's squad expected to turn out.

Amazingly, it will also mark the allrounder's first time against a pink ball under lights, a week out from the day-night Test against India in Adelaide.

"I've never actually faced it for before, whatever reason I keep dodging the day-night games in domestic cricket," Green said.

"There are a lot guys in the team who have played with the pink ball before. So I try and bounce as many ideas off those guys as I can.

"A few guys say if you are batting at night but already in, it seems like it's OK. It's just when you are new to the crease it will be tough.

"I have a training session today and it will be the first time I have ever faced it or bowled with it. That will be pretty interesting."

Green remains realistic about his chances of earning a debut in Adelaide next week.

He described Australia's middle order as "settled", noting David Warner's injury and Will Pucovski's concussion concerns at the top were unlikely to affect him.

The man described by Greg Chappell as Australia's best talent since Ricky Ponting has also made a point to avoid media hype around himself, in a bid to remain grounded.

That must be growing harder though, with Both Michael Clarke and Alan Davidson also joining the chorus of support for the young prodigy on Wednesday.

Realistically, it could be the case that Green's best chance comes later in the series, if Australia want an extra bowler or middle-order troubles.

But there will no doubt be plenty of eyeballs on the West Australian, who could still become an irresistible pick for Adelaide if he produces another big tour match.

"I'm sure most guys would say the same, you never really know if you are ready," Green said.

"All I can really do is just play well in the next game. It's going to be another tough challenge playing a full-strength India side in the pink ball in Sydney.

"I'll see how I go, just keep trying to perform and it will be up to the selectors to decide that."

Meanwhile Green said his body had pulled up well after the first tour match, but there was no immediate plans to increase his limit of four overs per spell on return from back injury.
