Cricket Australia hope the Test summer's bio-bubble will be enough to secure players an exit from Brisbane and a quick path back to the Big Bash League.
Skipper Tim Paine has highlighted uncertainty over his squad's future beyond the end of the fourth Test at the Gabba, thanks to their stint in Sydney and Brisbane's recent lockdown.
CA have begun preliminary talks with state governments about exemptions for entry, but will wait to confirm which Test squad players want to play in the BBL.
David Warner and Steve Smith headline players keen for a break at the end of the Test series, having spent the better part of five months inside biosecurity bubbles.
Paine, Marnus Labuschagne, Mitchell Starc and Nathan Lyon are some of the Test players who signed up for BBL cameos if they are still fit, before further tours.
Fellow squad members Travis Head, Moises Henriques, Michael Neser, Mitchell Swepson and Sean Abbott would likely be desperate to have a BBL game as soon as next week.
But Brisbane's recent lockdown triggered a fresh round of border restrictions, meaning travel from the city to Adelaide and Melbourne - both slated to host BBL games - is currently not viable.
"We're waiting to find out if we can go home," Paine said on Thursday.
"Or we are going to the Big Bash, or we're staying here in quarantine, or we're going somewhere else.
"It's nothing we can control."
Working in CA's favour is that the players have not been able to leave their hotels while in Sydney or Brisbane, except to travel to the ground for training or playing.
CA earlier this month was able gain the likes of Aaron Finch free passage into Perth, despite being in Melbourne when a hot spot was declared there by Western Australia.
Defending champions Sydney Sixers, who top the BBL table, will enhance their status as title favourites if they regain captain Henriques, Starc, Lyon and Abbott.
Meanwhile talks will ramp up next week over which cities will host finals.
Ideally CA would like higher-ranked teams to host, however Brisbane's lockdown, Sydney's COVID-19 cases and Perth's closed borders will make that difficult.
With the Sixers first and Thunder second, there is some hope that at least the final could be played in Sydney if numbers continue to drop in the city and either team qualifies.
