Veteran Wallabies prop Benn Robinson has been recalled to Australia's squad for their two-match Rugby Championship tour of South Africa and Argentina.

Second-rower James Horwill has also been included in the 28-man squad and named as captain ahead of Ben Mowen after overcoming a slight hamstring strain.

Uncapped Queensland Reds pair Albert Anae and Chris Feuai-Sautia are the other new inclusions with Brumbies loosehead Scott Sio and flanker Liam Gill paying the price for the Wallabies' 1-3 start to the tournament.

Overlooked by coach Ewen McKenzie at the start of the Rugby Championship, Robinson has been brought back to stabilise the shaky Wallabies scrum after impressing in Sydney club rugby for Eastwood.
