It's the second year in succession that the race won't take place.
The F1 Australian Grand Prix's been cancelled for the second year running because of – what are being called - "restrictions and logistical challenges" caused by coronavirus.
The Melbourne race usually opens the season but it was moved to November with the hope it could take place.
But the decision's now been made to scrap it from the calendar for 2021.
The Moto GP race at the venue has also been cancelled.
