fp1 saw Ferrari’s Charles Leclerc set the fastest time in opening practice at the Australian Grand Prix in Melbourne, with Lewis Hamilton second and a late lap that put Leclerc 0. 469 seconds clear. The session revealed close early pace among the leaders and exposed reliability problems that limited running for several teams. Teams and drivers scrambled for data as the opening day produced mixed running across the field.
Fp1: Leclerc sets the early benchmark
Charles Leclerc emerged fastest in the opening practice outing, displacing Lewis Hamilton with a late flyer that left him 0. 469 seconds clear of the seven-time champion. Until that final effort, less than 0. 1 seconds separated Hamilton, Leclerc and Max Verstappen, underscoring a tightly bunched top end of the order. New entries and younger drivers marked solid early showings: Isack Hadjar set the fourth-quickest time, 0. 820 seconds off the pace, while 18-year-old Arvid Lindblad made his debut with a competitive result for the Racing Bulls team.
Trouble across the paddock and mixed running in fp1
The fp1 session also highlighted significant reliability concerns. Aston Martin suffered badly: Fernando Alonso was unable to run at all because of a Honda power-unit problem, and team-mate Lance Stroll completed just three laps before an engine issue was discovered. Team principal Adrian Newey said that vibrations from the Honda engine were so severe that Alonso felt unable to risk more than 25 laps without potential long-term harm to his hands, a claim that framed the session as much about survivability as speed.
Mercedes had a low-key session; George Russell finished seventh, 1. 104 seconds off the top and behind McLaren’s Oscar Piastri. McLaren struggled with gearbox problems and world champion Lando Norris was down the order in 18th place. Kimi Antonelli ran to eighth fastest, ahead of the Audi of Gabriel Bortoleto, with Nico Hulkenberg taking the final spot inside the top 10. Esteban Ocon was 11th, separated from team-mate Oliver Bearman by Carlos Sainz and the second Racing Bull of Liam Lawson. The new Cadillac entry avoided the expected last-place spot thanks to Aston Martin’s issues, with Sergio Perez 19th and Valtteri Bottas 20th on the timing sheets.
What comes next as teams process fp1 data
fp1 is only an opening snapshot: practice sessions typically conceal different fuel loads and engine modes that shape lap times, so teams will use the remaining track time to refine setups and assess reliability. The weekend continues under the event-centre schedule running across the stated event days, and teams must resolve power-unit and gearbox concerns before qualifying and the race. Expect engineers and drivers to prioritise long runs and troubleshooting in the next sessions as they convert the limited early data into clearer performance predictions.
