Max Verstappen will be heavy favourite to make it three wins from three this season as his Red Bull team attempt to put weeks of paddock intrigue behind them at the Australian Grand Prix.
The Dutch three-time world champion emphatically led home teammate Sergio Perez in Bahrain and Saudi Arabia, but the celebrations were overshadowed by team disunity and allegations against Christian Horner.
The long-serving Red Bull boss was cleared of inappropriate conduct involving a woman colleague ahead of the season-opener in Sakhir and tried to put a lid on the drama in Jeddah.
But the unnamed woman has appealed to Red Bull GmbH, the parent company of the all-conquering Formula One team. She has also reportedly lodged an official complaint to Formula One's governing body the FIA, ensuring the saga will rumble on in Melbourne this weekend.
