Tevita Kuridrani and Israel Folau are the frontrunners for the Wallabies midfield positions for their match against England this weekend.
With Samu Kerevi also in the mix, Coach Michael Cheika has hinted that Kuridrani may be the obvious choice for outside centre largely because of his defence.
Kuridrani has played in every test match since Michael Cheika became the Wallabies coach.
The Fiji-born centre said the competition of Samu Kerevi and Israel Folau has added extra motivation but his focus was simply on continuing to work hard.
Four players with links to Fiji are in the Wallabies squad for the England test series.
They are Samu Kerevi, Tevita Kuridrani, Eto Nabuli and Taqele Naiyaravoro.
Australia will meet England at 10pm Saturday.
