The gruelling schedule of international matches at home began on Wednesday, with the first of three Twenty20 matches against South Africa.
That will be followed by five one-day internationals against the Proteas, a four-Test series against India and a limited overs tri-series involving England and India before the one-day World Cup in February-March.
Pat Cummins, who has played little in the last three Australian seasons through injury, made an encouraging return to international cricket in Wednesday's T20 loss to South Africa.
Test paceman Ryan Harris, meanwhile, returned to action this week after being sidelined since his match-winning efforts in the Cape Town Test against South Africa back in March.

Clarke said Australia's disastrous two-Test hammering by Pakistan in the United Arab Emirates this month would serve to spark the players in all forms of the game.
"I guess that's extra hunger and fire in the belly for us as the Australian team, to make sure we're at the top of our game, whether it be T20, one-day cricket or Test cricket," he said.
