At least one person has died and a number of others have been taken to a Darwin hospital after a traffic crash in the Kimberley region of Western Australia.

Police allege a Toyota Landcruiser carrying 15 people rolled in Halls Creek about midday yesterday.

According to police, no-one on board was wearing a seatbelt.

An injured woman was taken to Halls Creek Hospital but died later in the afternoon.

Authorities say the Royal Flying Doctor Service coordinated the transfer of at least four patients to Royal Darwin Hospital, including a boy, aged 9, and a 55-year-old woman.

At least two passengers have suspected spinal injuries.
