Western Force winger Nick Cummins has replaced Henry Speight in Australia's squad after he withdrew on compassionate leave.
Speight has travelled to Fiji following the death of his grandfather.
The Brumbies winger was suspended for the Wallabies first two games of the Rugby Championship after his red card and suspension following a dangerous tackle against the Stormers.
Cummins has travelled with the rest of the 40-man squad for a five-day training camp in Caloundra ahead of the first game against South Africa in Brisbane on July 18.
Cummins scored one try in 13 games for the Force in 2015.
