The 2018 Australian Grand Prix was a Formula One motor race held on 25 March 2018 in Melbourne, Victoria. The race was contested at the Melbourne Grand Prix Circuit and was the first round of the 2018 FIA Formula One World Championship.

Lewis Hamilton started the race from pole – his seventh pole position in Australia, a record for the event – while Vettel successfully defended his race win, the 48th of his career and stood on the podium for the 100th time. The race was also the first race since the official introduction of the halo cockpit safety device.

This was the first race without a Brazilian driver since the 1982 San Marino Grand Prix.
