A woman has reportedly died after the car she was driving on the Great Ocean Road, in Victoria’s south, went off a cliff and into the sea on Wednesday.

The ABC reports the woman was the only person in the vehicle.

Police say the crash happened about 1.20pm on Wednesday opposite Broadbent Road, near Lorne.

The woman’s car careered over a cliff and into the sea.

“The yet-to-be-identified female has been recovered from the car deceased and there were no other occupants,” a police spokesperson said.

“The cause of the crash is yet to be determined and the investigation is ongoing.”

An SES spokesperson said earlier a “very serious incident” had occurred along the coastal road.

The woman’s vehicle was upside-down in the water when crews from multiple emergency services arrived on the scene.

Victorian SES volunteers from Lorne and Winchelsea secured the car to prevent the tide from taking it away.

A high-angle rescue team was involved in the operation.

Heavy haulage was on the scene by late on Wednesday afternoon.

A CFA spokesperson said vehicles had responded from multiple stations nearby, including Anglesea, Apollo Bay, Geelong, Lorne and Aireys Inlet.

About a dozen emergency vehicles remained on the scene about 5pm on Wednesday.

Anyone who witnessed the crash or anyone with dashcam footage is urged to contact Crime Stoppers.

The heavily trafficked Great Ocean Road has been closed between Eastern View and Lorne.

The Victorian Department of Transport has urged motorists take the inland detour through Winchelsea and Deans Marsh.
