Northern Territory Police are at the scene of a fatal crash near the town of Jabiru, approximately 220 kilometres east of Darwin.

The single vehicle rollover on El Sharanda Road was reported to Police at 6:35am this morning.

Jabiru Fire and Rescue members found two occupants in the Holden Commodore, which was upside down and extensively damaged.  A female had died and a male remains in a critical condition.

Police are in the process of identifying the two people they believe are in their late teens or early twenties.

Watch Commander Louise Jorgensen said the man had been transported to the Jabiru clinic and it is expected he will be flown to Darwin with Careflight.

“It is still too early to determine the cause of this crash but it appears that speed may have been a contributing factor.   The car has hit a concrete slab and initial observations suggest the occupants were not wearing seatbelts at the time.”

Senior Sergeant Jorgensen said it was tragic to lose anyone in a crash but even more so this close to Christmas.

“There will be a family in mourning this Christmas because of this crash.  We implore every road user to slow down, wear seatbelts and drive to your abilities and to the road conditions.”

The road toll now stands at 45 compared to 37 at the same time last year.
