Henry Speight and Rory Arnold are among six new players called up to the Wallabies squad for the upcoming Tests against the Boks and Argentina in September.

Speight returns to the Test squad after a stint with the Australia Sevens side at the Olympics, while Arnold earned a recall after recovering from an elbow injury.

Coach Michael Cheika has selected four uncapped players in the group. They are Sefa Naivalu (only eligible to play on 18 September), Kyle Godwin, Lopeti Timani and Tom Robertson.

The Wallabies have lost a core group of experienced players with Matt Giteau, Ben McCalman, Matt Toomua and Rob Horne all out due to injury, while veteran Adam Ashley-Cooper left the camp to return to his French Top 14 club Bordeaux.

Meanwhile, utility back Luke Morahan has been declared fit and is also available for selection against South Africa.
