Adelaide woman dies after fire rescue

A woman has died in hospital after being rescued from a house fire in Adelaide in the early hours of Friday.

Fire crews were called to the home at Hazel Terrace at Henley Beach South just before 4am, but were initially told by neighbours that no-one was inside.

The only occupant, a 50-year-old woman, was treated at the scene by paramedics before being taken to the Royal Adelaide Hospital.

She died from her injuries on Friday night.

"We still had mixed messages when we arrived from some of the neighbours saying there was no-one living there so we were assured by that," a fire crew member told the Nine Network on Friday.

"We thought that's a good thing and then obviously we found her into the job."

Fire cause investigators have determined the fire's cause is not suspicious.
