The FIA and stewards were kept busy during the 2025 season opener in Melbourne, with wet weather and driver errors causing multiple safety cars and subsequently several investigations.
Lewis Hamilton was scrutinised by the stewards for a safety car infringement alongside three other drivers, but all four managed to escape a penalty as the FIA did not take any further action.
However, during the latter stages of the race the rain began to fall with drivers hurtling into the pits for wet weather tyres, which prompted a series of unsafe releases.

The first driver to be penalised for an unsafe release was Sauber's Gabriel Bortoleto, who received a five-second time penalty when he was released into the path of Liam Lawson forcing the Kiwi driver to take evasive action to avoid a collision.
Towards the end of the race Kimi Antonelli was also placed under investigation, with the Mercedes star having made his way up from the back of the grid to P4.
However, the team were responsible for an unsafe release into Nico Hulkenberg, who had to brake to avoid contact, and Antonelli was promptly dished out the same five-second time penalty as Bortoleto.
As a result Antonelli dropped to fifth but still celebrated the result, and alongside George Russell's podium finish, helped secure second place for Mercedes in the constructors' standings, just two points shy of McLaren.
