Supercars officials will prioritise new street circuits at home over the potential of global expansion, with Australia and New Zealand the main focus for bosses.
It was confirmed on Thursday that Supercars would remain part of the Australian grand prix for the next three years, with a deal through until the end of 2029.
The format has previously raced in China, Bahrain, the UAE and US this century, with the most recent race outside of the Pacific being in Texas in 2013.
Officials had put overseas expansion beyond New Zealand back on the agenda in 2024, with Singapore mooted as a potential option alongside the F1 GP.
One of the advantages of adding Supercars to an F1 weekend is that it allows it to be promoted as a full four-day event for grand prix organisers, rather than three.
But CEO James Warburton confirmed on Thursday that Supercars now had their eyes closer to home.
"We've talked about levels of global expansion. We have talked specifically with a lot of promoters," Warburton said.
"But our show is complicated, there is a lot of freight, a lot of people and a lot of equipment to move around.
"Our focus is about making sure our Australian and New Zealand product is as strong as it could be."
As things stand, there are 12 events in Australia and two across the Tasman, with the Taupo and Christchurch double next month.
Work has begun on a street circuit in Perth, with officials aiming for a 2028 entry.
Melbourne, Gold Coast, Adelaide and Townsville already host races on their city streets, while events at Newcastle and Sydney Olympic Park have since fallen off the calendar.
However officials are keen to return a street circuit to NSW for a third race in the state, with Central Coast and Wollongong floated as options.
"We've got a couple of big street circuits that we're investigating, so for us it's about continuing to grow into the dominant No.3 sport in this country," Warburton added.
