A 29-year-old woman was killed in a crash on Easter Sunday

The incident occurred on Easter Sunday, about two kilometres south of the Bell Bay power station, where police and emergency services were called to the scene around 6.30am.

Tasmania Police Inspector Luke Manhood said they believed she was thrown from the car as it rolled.

"In this case the driver was ejected from the vehicle likely because she wasn't wearing a seatbelt," Inspector Manhood said.

"The cause has yet to be determined but a report for the coroner and from our car crash investigation team are being prepared."

He said the woman was travelling north on the East Tamar Highway in a silver Mitsubishi Magna when she lost control of the vehicle.

"A silver Mitsubishi Magna was travelling north on the highway when it lost control on a sweeping left hand bend and then crashed on the right-hand side of the road," Mr Manhood said.

"The driver who was the sole occupant sadly died."

Mr Manhood said the family of the deceased was present at the scene this morning and was spoken to by police.

"This is our 10th fatality for this year, it's only just under where we were at this time last year," he said.

"We really need every driver to pay attention"
