The basic track changes see the parts of the circuit enlarged, the chip of turn 9-10 removed to increase speeds in a flowing rear section and the entire assembly has returned to the surface. All the changes were made in the hope of increasing overtaking opportunities and creating more exciting races. Sebastian Vettel returned to Aston Martin after losing the first two races after being tested positive for COVID-19 and had an eventful Friday following an engine failure in FP1 that knocked him out of second training, while also receiving a € 5,000 fine for driving a scooter on the track back in the pits after FP1. F1 World Championship leader Charles Leclerc completed Friday’s training session for Ferrari with Red Bull’s Max Verstappen after Carlos Sainz Jr. was the fastest in FP1. The final training session for the Australian GP starts at 4 p.m. BST (1 p.m. local time), followed by qualifying at 7 p.m. BST (4 pm local time).
