Quade Cooper is reportedly set to announce a four-year deal to remain in Australian rugby which allows him to play at the Rio Olympics.
Fairfax Media reports that the Wallabies five-eighth will turn his back on a rich offer from French powerhouse Toulon before settling on a Super Rugby franchise for the 2017 season.
Cooper produced an indifferent display in Australia's 24-20 victory over South Africa in the Wallabies' opening game of the Rugby Championship in Brisbane.
His halves partner Will Genia was equally unimpressive, before leaving the field at half time with a knee injury.
On Sunday, his coach Michael Cheika revealed Genia will miss the Wallabies next game in Argentina.
"Will's just got a little bit of bone bruising and a little bit of cartilage on his knee," Cheika said.
"So he'll need seven to 10 days off feet and then back into rehab after that. So the Bledisloe series is a realistic mark for him.
The Australian winger Rob Horne will also miss the plane after aggravating a calf problem during the Wallabies' last-gasp 24-20 win at Lang Park.
Cheika has summoned winger Nick Cummins and scrumhalf Nic White back from the United States to provide cover, where they have been promoting Australia's World Cup warm-up match in Chicago.
In other changes to his squad, uncapped winger Taqele Naiyaravoro and lock Rory Arnold will be staying in Australia, while hooker James Hanson and prop Tetera Faulkner, who can cover both sides of the front row, have been brought in.
Australia were second best to South Africa for much of Saturday's match and needed a try after the hooter from Tevita Kuridrani to secure the win.
Cheika said the Wallabies were aware they had to improve ahead of next weekend's game if they were to avoid losing to the Pumas in Mendoza for a second year in a row.
