Big Bash leaders the Sydney Thunder and Sixers could be denied the chance to play in front of their home fans after three games were moved to Canberra.
Officials confirmed on Friday games on January 13, 16 and 18 would move to Manuka Oval due to Sydney's COVID-19 outbreak, with five more matches still up in the air.
CA last week made the call to push on with the Sydney Test, but border crossings have made playing BBL games in the city near impossible.
"The logistical complexities of the BBL ... means moving these games gives us the best possible chance of executing a full season," BBL boss Alistair Dobson said.
"This differs from the logistics of the ongoing Test Series, which requires fewer movements across state borders to execute a full series.
"As part of our ongoing monitoring of the situation in Sydney, we will consider whether or not we need to make any decisions on the remaining matches in Sydney."
But as has so often been the case this summer, just as CA put out one spotfire another threatened to erupt.
Queensland's three-day lockdown threatens to heavily impact the BBL, given it is applicable to anyone who has been in Brisbane since January 2.
While all BBL teams playing in Queensland have stayed on the Gold Coast, the Sydney Sixers, Thunder and Brisbane Heat have all played in Brisbane since that date.
The Sixers and Heat play again on the Gold Coast on Sunday and at this stage officials expect that to go ahead with a crowd though those from Brisbane will be barred.
Meanwhile the Thunder, currently in Perth ahead of a clash with the Scorchers on Saturday, could pose another problem.
Western Australia almost immediately closed their border to Queensland on Friday, again back-dating it to anyone who had been in the state since January 2.
It means CA will need to secure exemptions to have them allowed out of their hotel rooms, with all travellers to Western Australia from Queensland required to undergo 14 days' quarantine.
Working in their favour is the fact they were able to secure similar exemptions for the Renegades and Sixers last week after both had players or coaches from Melbourne.
"Obviously anyone who has been in Queensland is now a concern if they have been there since January 2," Western Australia Premier Mark McGowan said when asked about the Thunder.
"We will have protocols in place for all of those people to be quarantined and tested."
