One dead, four injured in NT crash

One person is believed dead and four others, including a child, are critical after a vehicle rolled in the outback, near the Northern Territory-South Australian border.

Three adults and one child were evacuated from the scene near Kulgera by two Royal Flying Doctor Service crews this morning.

They were all taken to Alice Springs Hospital.

"Reports at the scene say a fifth person involved in the accident is deceased," a RFDS spokeswoman said.

Kulgera is located in the Northern Territory, about 20km north of the South Australian border.
