Supercars is set to unveil an 11-round revised 2020 schedule on Sunday morning.
With coronavirus restrictions beginning to ease around Australia, the series has been able to settle on a revised calendar to complete the 2020 season.
Last month Supercars officials had plotted a best case scenario of returning to action in June but with a series of restrictions including revised formats, no pit-stops, two-day race weekends and TV-only media.
There will be 11 more rounds, making for a total of 12 including the Adelaide 500 - two short of the original 14-event schedule.
Action is expected to kick off in either late June or early July, Sydney Motorsport Park among the rumoured venues to host what would be the second round of the 2020 season.
"If we're talking mid-May [for an announcement], the earliest we could get going is June," series boss Sean Seamer said earlier this month.
"You can deduce that if we're talking about announcing what our plans are on the 15th of May, it will take a period of time for the teams to be able to mobilise.
"So without speculating, I think you can quite quickly do the math to figure out the soonest we can get going is June."
Townsville is set to be retained as the only street circuit, with Gold Coast and Newcastle thought to be the events unlikely to go ahead.
The postponed trips to Perth and New Zealand are expected to be rescheduled to later in the year, with the Western Australia event set to take place in November and the journey across the Tasman sea delayed until next January.
The season will then finish with a second visit to Mount Panorama for a sprint round in place of the Bathurst 12 Hour.
Final decisions on formats are set to be delayed but there has been speculation from the paddock that there will only be one enduro - the Bathurst 1000.
