Wallabies coach Michael Cheika has named three new faces amongst a 31-man squad to face South Africa and Argentina over the next fortnight.

Newly crowned Brumbies Player of the Year Rory Arnold as well as Reds pair Brandon Paenga-Amosa and Caleb Timu will join the Wallabies squad ahead of the Test against South Africa at Suncorp Stadium next Saturday night.

Arnold is yet to feature in 2018 while Paenga-Amosa started all three Tests in the number two jersey against Ireland after impressing for Queensland in Super Rugby.

Timu bounced back to his barnstorming best with a try for Queensland Country in yesterday’s grand final replay against the Canberra Vikings in the National Rugby Championship.

Israel Folau (ankle) has been named in the squad after missing the second Bledisloe Cup Test in Auckland while prop Taniela Tupou (hamstring) is also racing the clock to be fit for Saturday night’s Test against South Africa in Brisbane.

The Wallabies will reconvene on the Gold Coast later today ahead of the clash at Suncorp Stadium before they take on Argentina at Cbus Stadium on the Gold Coast on September 15.

Australia currently sit fourth in the Rugby Championship after back-to-back defeats to New Zealand.
