Head coach Ewen McKenzie has called up Waratahs winger Peter Betham to his 32-man Wallabies Rugby Championship squad as Brumbies flyer Henry Speight is injured.
Speight has a hamstring injury and is expected to be sidelined for a month having suffered the injury playing for the Brumbies in the second half of the Super Rugby Semi-Final clash against the Waratahs at Allianz Stadium.
Fijian born winger Speight becomes eligible to play for Australia on the 11th of September and has been replaced by Betham who earned his international debut for Australia in the third Bledisloe Cup Test against New Zealand in Dunedin last year.
"It's disappointing for Henry but I've got no doubt that he'll go back and work hard during the rehab process to get his injury healed before he becomes eligible to play for Australia in mid-September," said Wallabies coach Ewen McKenzie.
"On the flip side, we bring in a guy in Peter Betham who has had significant exposure to our program over the past year and who made his Test debut against New Zealand in 2013.
"He's a quality team member on and off the field and will be determined to make the most of the opportunity he has been given."
The Wallabies, minus the Waratahs players participating in the Super Rugby Final, will assemble on Sunday 3 August to begin their week-long regional road trip across Dubbo, Orange, Bathurst and Penrith.
The Waratahs representatives in the Wallabies squad will join the team in Bathurst on Wednesday 6 August.
