Fourteen people have lost their lives in accidents on Australian roads over the Easter long weekend following the death of a man in a single-car rollover in Victoria.

The man driving the car that fatally rolled at a Wangaratta intersection late on Sunday is under police guard in a local hospital with suspected non-life-threatening injuries.

Victoria Police said one of the man’s three male passengers died after the car rolled into a paddock.

The other two men were airlifted to hospitals in Melbourne with critical injuries.

The death in Wangaratta is the latest since a devastating start to the Easter long weekend, which began with seven road deaths on Good Friday.

These included four adults who were killed in a crash in the Southern Tablelands in NSW and a woman in Tasmania who was a passenger in a sedan.

A 26-year-old woman has been charged with causing death by dangerous driving after her Toyota Camry collided with a white MG near Copping, east of Hobart.

Two people were killed in separate incidents within 24 hours in the Northern Territory, including a man involved in a collision between a motorbike and quad bike on the Finke Track.

The 27-year-old quad bike rider died at the scene, while the 24-year-old male motorbike rider has been flown interstate for treatment.

Another man died in the early hours of Saturday in a single-car rollover involving four adults near Hermannsburg, west of Alice Springs.

There were three more fatal accidents in regional areas of Western Australia, South Australia and Tasmania on Easter Sunday, one of which involved a 16-year-old boy.

The teenager was killed early on Sunday when a Honda station wagon collided with a tree about 75km south of Adelaide.

Early investigations into the Tasmanian crash indicate a 29-year-old woman lost control of a Mitsubishi Magna on the East Tamar Highway at Bell Bay on Sunday morning.

A 59-year-old man died in a fatal crash two hours south of Perth when a Mitsubishi Pajero left the Bussell Highway and collided with a tree.
