The 35-year-old Brit drove Anton De Pasquale’s DeWalt entry at the Grand Prix venue on Wednesday afternoon with the Australian in the passenger seat.
The outing took place to film a piece for F1 TV, with which Palmer works as an analyst and commentator.
Palmer, the 2014 GP2 Series winner, contested 35 Grands Prix for the Renault F1 team across the 2016 and ’17 seasons.
He’s since transitioned to broadcasting and featured on an alternate commentary stream carried in Australia by Kayo Sports in the second half of 2025.
Palmer’s career has followed that of his father, Dr Jonathan Palmer, who made 83 F1 starts during the 1980s before also making the move to commentary.
The Team 18 laps marked the latest crossover between F1 and Supercars in Australian Grand Prix week.
