Townsville will host consecutive Supercars events for the second successive year after organisers pushed back Sydney's leg due to NSW's ongoing COVID-19 concerns.
Back-to-back events will be held in the city with the Townsville 500 between 9-11 July and the Townsville SuperSprint on July 17-18.
A total of five races will take place over the next two weekends.
The Super trucks, Super2 Series, Carrera Cup and Gazoo Racing 86 Series will all be held this weekend with the combined Super2 and Super3 Series racing again next weekend, organisers confirmed on Thursday.
"Following the success of last year's inaugural double-header, we know two weeks of racing in Townsville allows us to maximise exposure and competition during these times," Supercars CEO Sean Seamer said.
Championship leader Shane Van Gisbergen says the fast-paced circuit and knowledge from last year's double header will benefit all drivers over the two weekends.
"This track and how intense it is - you get a short straight but then the rest of it is just flat out so it's going to be tough, he said.
"Everyone knows this track quite well ... and the cars are so close this year, so certainly this type of track and the two race formats each weekend it's a bit of variety which is good."
Queensland's Tourism Minister Stirling Hinchliffe said the back-to-back events were a win for the region.
"The Supercars double-header is a perfect excuse to pack a bag for Townsville and beat the winter chills," Hinchliffe said.
"We know events like the NTI Townsville 500 brings tens of thousands of extra visitors to the North."
Van Gisbergen leads the 2021 championship standings with 1361 points with Chaz Mostert and Jamie Whincup hot on his heels in second and third respectively.
