Calendar changes

 * The original calendar removed the Ipswich, Newcastle and Perth rounds with Sydney Motorsport Park and Symmons Plains reinstated, having last being in the series in 2017 and 2018 respectively.

The series was to have seen an increase in the prize money awarded, with the champion to be given $400,000 as a way to secure funding into the Supercars Championship. A "Rookie" class aimed at drivers under the age of 25 was planned, with the winner to be awarded $100,000 to secure a second year in the series.
