At the peak of its popularity when IndyCar was involved, the government pumped $12 million into the Gold Coast race, which now receives about $4 million-a-year.
The temporary Surfers Paradise street circuit and precinct costs $10 million to erect and dismantle while the Townsville event costs more than $6 million.
With Townsville's economy struggling, Supercars officials believe the events cannot feasibly run with the funding proposed by TEQ.
It would be a bold call for the government to not come to the party given the three events pump up to $90 million into the state's economy.
If Queensland was to be shunned, it would also see some of the category's top teams move interstate.
Brisbane-based Triple Eight Race Engineering has been the most successful team of the past decade, helping Jamie Whincup to six championship wins.
"It's absolutely paramount we keep these races," said Triple Eight boss Dane.
"We will not only be bitterly disappointed if we don't run at Townsville and the Gold Coast but it will also have serious implications for our businesses.
"There's no question (we would move), if only because of the logistics.
"If you're coming in and starting from scratch, you're not going to put yourself in south east Queensland.
"Will it happen tomorrow? No, but it will happen.
"There'll be gravitation to the south and temptation to set up in western Sydney and Adelaide where both state governments have made it clear they'd welcome us with open arms."
TEQ spokeswoman Megan Saunders said taxpayers' money had to be invested wisely.
"A substantial offer is on the table and we look forward to the discussions continuing," she said.
"Our objective is to get the most effective outcomes for taxpayers' investment.
"TEQ recognises the importance of the Gold Coast and Townsville as tourism and events destinations and we remain committed to delivering the best events for the community.
"Our focus is on driving more visitors to the state to deliver direct economic and community benefits for Townsville.
"It is important as events become more mature and commercially attractive that taxpayers investment is aligned accordingly."
Dane said it was particularly important for the Townsville event to continue to help boost the region's battling economy.
