Dewald Brevis has not been selected with Matthew Breetzke, David Miller and Tristan Stubbs preferred as middle-order batting options.
Bjorn Fortuin and Keshav Maharaj are the two specialist spin options in the squad.
“With the World Cup just over a year away, this series marks an important step in shaping the squad as we build towards the tournament, while also giving those players who are in the frame opportunities when we face Bangladesh and England later in the season,” coach Shukri Conrad said.
The series against Australia gets under way in Durban on September 24, before the second match in Johannesburg on September 27 and then Potchefstroom on September 30.
