Description
The Sandown 500 moved to a late-season slot in November, becoming the final round of the Pirtek Enduro Cup, to avoid clashing with the AFL and NRL finals series. The Auckland SuperSprint was brought forward to September, making the Sandown 500 the penultimate round of the championship. Changes to the Formula One calendar meant that the Australian Grand Prix was run earlier in the year than it was in 2018, and thus the Supercars support races was also moved forward. The Adelaide 500 was subsequently brought forward to remain the opening round of the season.
