Leicester Tigers duo Tatafu Polota-Nau and Matt Toomua have been included in a 36-man training squad by Australian head coach Michael Cheika ahead of the Wallabies' 2018 Bledisloe Cup and Rugby Championship opener on August 18.
Polota-Nau, who qualifies for international selection under Rugby Australia's overseas player selection policy rules for players with 60 Test appearances or more, has been named after being rested for the recent series against Ireland down under.
Tigers centre Toomua qualifies for selection, despite having only made 33 Test appearances, after it was announced earlier this week that he has agreed terms to return to Australia with the Melbourne Rebels in 2019 at the conclusion of the upcoming Northern Hemisphere season.
Last season's Leicester Tigers Supporters Player of the Year is currently in Australia and impressed Cheika with a 55-minute starring role in Friday's trial match between the Wallabies and a Super Rugby XV in Sydney, with Polota-Nau to meet up with his club team mate and the Wallaby squad in the coming days.
If retained in the final squad for the upcoming Bledisloe Cup and Rugby Championship series, the pair are expected to return to Tigers during the Rugby Championship rest periods, which coincide with rounds 1 and 4 of the Gallagher Premiership.
