Westacott, the chief executive of the Australian Grand Prix Corporation, reckons the 21-year-old Piastri’s appearance at the grand prix in his home city has boosted ticket sales by about 10 per cent. But Piastri and his McLaren teammate Lando Norris have struggled to make inroads in the opening two races leading into the Australian leg. But with West Australian Daniel Ricciardo not in a driver’s seat this season, Westacott said Piastri’s appearance was a boost for the Melbourne event. Supercars and Porsche Carrera Cup take to the Albert Park track on Thursday before F1 practice sessions on Friday, qualifying on Saturday and Sunday’s grand prix.
