Glenn Maxwell has been picked in the squad after ten months for the series against England, starting September 4.
The right-hand batsman and handy part-time option took a mental health break from the game last September, went through an elbow surgery and then had his break extended by the COVID-19 pandemic.

Maxwell's only cricket in this period has been leading Melbourne Stars to the final of the BBL '09 final last home summer.
When the training resumed, the 31-year-old went through the drills with fellow Victorian Finch, the conversations with whom gave him a much-needed morale boost and clarity with regards to his role ahead of the England tour.
"(I've been) really working with Aaron Finch and the coaching staff with my role in the side and committing to that 100 per cent every time," Maxwell was quoted as saying by cricket.com.au. "It's going to be more of a finishing role this time."
"And to have the confidence from Finch and the coaching staff that I can perform in that role is great," he added. "I've been away from the game for a while now and to come back and have that backing is awesome. I just hope I can do it as well as I can."
Maxwell's last outing for Australia before he opened up on his mental struggles saw him blast his way against Sri Lanka in a T20I and he looked a certainty for the now-postponed T20 World Cup.
In the ODIs, he was dropped even after making himself available again when selectors went about picking a team for this January's trip to India and hasn't featured since the end of Australia's 2019 World Cup campaign.
However, despite question marks still looming whether he can ever be a consistent success in the 50-over game, Maxwell remains upbeat and is eyeing a ticket to India for the 2023 World Cup.
"I certainly haven't played a lot of one-day cricket recently. I'm just looking forward to getting back out there in the colours and performing as well as I can in whatever role I'm given," he said. "I'm confident in the skills work that I've done in the off-season and I'm ready to go."
Maxwell has been working harder on his off-spinners to make himself more of an attractive commodity to the selectors, keeping in mind the Indian conditions for the ODI World Cup, and even the next T20 World Cup in 2021, given it has been moved outside Australia.
"I've done a lot of work on my bowling in that time away, trying to be that genuine allrounder where I can bowl upwards of six, seven, eight overs a game to really take the load off the quicks and the front-line spinner if we do play one," he said.
"To go back to that 2015 year when I was the sole spinner (at World Cup) and I was relied heavily upon, to be able to get back that string to my bow where I'm bowling a lot of consistent overs and helping the team out wherever I can," Maxwell concluded.
