Melbourne-based Supercars teams are now facing isolation if they escape Victoria today, due to a change in the New South Wales border rules.
The six Melbourne teams are all considering relocating to NSW as soon as today to avoid the seven-day Victorian lockdown that will start at midnight.
That would have allow them to spend the next two-and-a-bit weeks in NSW and then freely travel to the Northern Territory for the Darwin Triple Crown next month.
A number of the teams, including Tickford and the Blanchard Racing Team, were set to get moving later today, however a fresh change to NSW's border stance may scupper those plans.
Anybody crossing into NSW from Victoria from 4pm local time today will be forced to serve 14 days of self isolation.
