the year, the championship was contested over eleven rounds, although racing only occurred at ten rounds. Calendar changes The Sydney SuperNight was originally scheduled to return to the calendar after a one-year absence, but was instead be the first event back after the enforced break due to the COVID-19 pandemic, and ran in daylight hours. Sydney Motorsport Park continued to host the event. The Gold Coast 600 was to have also become a night race. The Auckland Super400 moved from Pukekohe Park Raceway to Hampton Downs Motorsport Park. The change was made in response to Auckland Council passing legislation that prohibited from running any event at the circuit on key dates, with Anzac Day falling on the Saturday of the round. The Bend 500 was scheduled to replace the Sandown 500 as the opening round the Enduro Cup. The Bend SuperSprint was re-formatted as a 500 kilometre race, while the Sandown round adopted a sprint format, called the Sandown Super400. This resulted in a 500 kilometre being restored as the first race of the Enduro Cup after the Bathurst 1000 was the first endurance race in 2019. The Ipswich and Phillip Island SuperSprints were removed from the calendar. It was the first time since opening that Queensland Raceway has not been on the calendar and the first since 2004 for Phillip Island Grand Prix Circuit. Format changes The Saturday race at the SuperSprint and SuperNight events and the Darwin Triple Crown were due to be extended from 120 kilometres to 200 kilometres. Proposed changes to the Melbourne 400 and a relocated Sandown 500 to The Bend Motorsport Park did not take place as the events were subsequently cancelled.

Supercars later announced the postponement of the Launceston, Auckland and Perth rounds due to the pandemic. All three were later cancelled. The championship recommenced in June with a reformatted round at Sydney Motorsport Park, with the postponed races assigned new dates later in the season.
