English engineer Burgess joined the organising body in October 2018 after working for several teams in the Supercars paddock.
He oversaw the arrival of Gen3 rules for 2023, although its first year has been dogged by grumblings over parity between the Chevrolet Camaro and Ford Mustang with the Blue Oval winning just four of 26 races in 2023 so far.
Announcing his departure, Supercars said that in addition to seeking a replacement head of motorsport it aims to hire a new technical director and performance engineer.
Paying tribute to Burgess's efforts, Supercars CEO Shane Howard said: “Adrian has made an invaluable contribution to our sport.
“To manage the motorsport and technical operations of one of the world’s leading categories is a challenging task, which Adrian has worked tirelessly on over recent years.
“He has been an integral part of the Motorsport Team and the business, contributing significantly over the past five years.
“We want to express our deep appreciation to Adrian for the dedication and hard work he has applied in advancing our racing product.”
