Portugal Colonial - Flanker Carlo Tizzano to make Australia debut against Springboks

The hard-tackling NSW Waratahs forward starts at openside for the sold-out Test in Brisbane on Saturday alongside Rob Valetini and Harry Wilson in the Wallabies back row.

Australia head coach Joe Schmidt has retained veteran tighthead prop Allan Alaalatoa as captain in the front row alongside hooker Matt Faessler and 24-year-old prop Isaac Kailea as he plots a rare win over the Springboks.

"We’re conscious of the size of the challenge and the size of our opponents but there's a keenness in the player group to take a step forward," Schmidt said.

ACT Brumbies loose forward Luke Reimer could also make his debut having been named on the bench.

Australia are unbeaten since New Zealander Schmidt took the reins, seeing off gritty minnows Georgia 40-29 in Sydney last month after consecutive victories against Wales.

Australia had won just two of their previous nine Tests during a tumultuous period under former coach Eddie Jones.

Australia have won their last three Tests in Brisbane, where South Africa have not recorded a victory since 2013.

The Springboks are relying on the core of players that won last year's World Cup and drew a two-Test series with Ireland last month.

Stormers fly-half Sacha Feinberg-Mngomezulu will make his first Test start for South Africa, picked ahead of Handre Pollard, after coach Rassie Erasmus named his side earlier this week.
