The Australian Grand Prix has been delayed by over two hours due to poor weather at Phillip Island on Sunday.
The last-ever MotoGP race at the iconic Phillip Island circuit was due to kick off at 2pm local time, but the pitlane will now open provisionally at 4pm, with a revised start time yet to be announced.
While Melbourne continues to witness heavy rain, lack of visibility remains the chief problem, preventing MotoGP's medical helicopter from operating. The championship rules require the helicopter to remain on standby should a rider need to be airlifted to hospital.
The organisers had to push back the start of track action several times through the day, and it wasn't until 2pm that they confirmed a time for pitlane to open.
"As we wait for visibility to improve, the new provisional pitlane opening time for the MotoGP Grand Prix at the Red Bull Grand Prix of Australia is now 16:00 local time," the championship said in a statement.
"Due to the delays caused by the poor visibility affecting the operation of the medical helicopter, the Moto3 and the Moto2 races have both been cancelled."
Track action for the day was due to kick off at 9:40am with the MotoGP warm-up. But the session was rescheduled to 11am before being cancelled. Moto3 and Moto2 races at Phillip Island were progressively cancelled through the day to prioritise the premier class.
Poor weather had been forecast throughout the weekend at Phillip Island, with conditions deteriorating on Sunday as expected.
There were discussions about MotoGP proactively altering the schedule at the start of the weekend, but no such changes were ultimately made.
All sessions on Saturday went ahead as per schedule, with qualifying taking place in wet conditions before the circuit dried in time for the sprint.
