Sydney: Coach Michael Cheika on Friday included three uncapped players in a 32-man Wallabies squad for their two remaining Rugby Championship Tests in South Africa and Argentina.
Queensland Reds lock Lukhan Tui, Western Force back Billy Meakes and Reds outside back Izaia Perese will be vying for their Wallabies debut over the next fortnight.
Reds flanker Adam Korczyk was dropped from the original squad, with Cheika preferring a slightly smaller touring party for the games in Bloemfontein and Mendoza.
The Wallabies depart for Johannesburg on Saturday as they aim to go one better against the Springboks in Bloemfontein following a 23-23 draw in Perth a fortnight ago.
Australia last played in Bloemfontein in 2010, when they snatched a last-gasp 41-39 win through a long-range penalty kick from Kurtley Beale after the full-time siren.
The Wallabies also won on their last visit to Mendoza back in July 2015, after 14 points from the boot of Bernard Foley secured a 34-9 win.
The Wallabies face the Springboks on September 30 and Argentina on October 7.
