The Shannon's Motorsport Australia Championship will return to The Bend Motorsport Park in 2021.
The sixth and final round of the championship will be raced on October 15 to 17.
Other races are scheduled to take place at Phillip Island, Bathurst, Sydney, Morgan Park (Queensland), and Sandown (Victoria).
Categories competing at the events are still to be confirmed, however motorsport fans can expect to see top level national motorsport, including the Porsche Michelin Sprint Challenge Australia, Motorsport Australia GT Championship, Motorsport Australia Endurance Championship, VHT S5000 Australian Drivers' Championship, carsales TCR Australia Series, Touring Car Masters, National Trans Am Series, Australian Prototype Series, Radical Australia, Australian Production Car Series and more.
Shannons Motorsport Australia Championships director Michael Smith hoped 2021 would provide more excitement than 2020 did with a lack of racing.
"We all know that 2020 hasn't allowed as much racing as we would have liked, particularly at the national level," Mr Smith said.
"With restrictions starting to ease around the country, the prospect of our 'Return To Race' is very real and the Shannons Motorsport Australia Championships calendar can be released with some certainty.
"The exact make up of each event is still to be confirmed, but we're working closely with a range of category managers to deliver a really exciting season of national motorsport."
He said a large group of people had worked hard to organise the events for 2021 calendar.
"Everyone is itching to get going again and the support for the Shannons Motorsport Australia Championships events in 2021 has been reassuring to us," he said.
Tickets for each event are available at the Shannons Motorsport Australia Championships website.
