Wallabies duo Matt Toomua and Tatafu Polota-Nau are off on a whirlwind journey this week.
Toomua and Polota-Nau travelled back to London on Sunday night while the rest of their teammates stayed in Australia.
As part of the regulation nine window, the pair must return to their club Leicester this weekend for the start of the Premiership before returning to Wallabies camp before their next Test.
Though the players are available for the full Rugby Championship, regulation nine stipulates that national teams can only call on them for six weeks of the full nine, meaning off weeks are spent back in their clubs.
Leicester plays Exeter in the first match of their season on Sunday at 1:30am AEST.
Theoretically, Toomua and Polota-Nau could play in that game and then be back in Wallabies camp by Tuesday with four days left to prepare for the Brisbane Test against the Springboks.
The pair will have to make a similar trip after the Wallabies' home Tests against the Springboks and Pumas, though the trip back from the UK won’t be as lengthy that time with the Wallabies playing South Africa away on September 29.
Polota-Nau started in both of the Wallabies Tests against the All Blacks, while Toomua had limited minutes off the bench.
