International endurance racing promoter Creventic has been added to the list of bidders for a new event at Bathurst.
The Bathurst Regional Council initially confirmed five parties had bid for a fifth Bathurst slot after the expressions of interest period closed on Tuesday afternoon.
But it has now clarified there were six bidders, as Creventic's proposal was initially overlooked as it was submitted via the council's email address rather than its online tenders portal.
Creventic, based in Holland, is the organising body behind the 24H Series, which runs 12- and 24-hour events for GT and touring cars across the world.
It currently stages a 'Champion of Continents' series that features 24-hour races in Dubai, Portimao, Barcelona and Austin.
A successful bid from Creventic would likely mean a return of twice-around-the-clock racing to Mount Panorama for the first time since 2003 when the Bathurst 24 Hour GT race was staged.
As reported on Tuesday, Supercars - which has proposed a Goodwood Festival of Speed-style event - and TCR Australia are among the bidders for the fifth event.
Should a fifth event become a reality, it will sit alongside the Bathurst 12 Hour, Bathurst 6 Hour, Bathurst 1000 and Challenge Bathurst.
