His first stop as CEO will be Adelaide, as the 2018 Virgin Australia Supercars Championship gets underway on March 1-4.
Following his appointment last November, Seamer attended the 2017 season finale in Newcastle in an unofficial capacity alongside Warburton.
The 20th year of Adelaide street race includes the debut of the all-new ECB SuperUtes Series.
It also marks the start of a Supercars season featuring points races at the Australian Grand Prix for the first time, the return of night racing at Sydney Motorsport Park and Tailem Bend’s addition to the calendar.
Supercars hit the track for the first time at 9:45am local time on Friday, with the year’s opening practice session.
