UPDATE: The Toowoomba community is rallying for a Wilsonton Heights woman who suffered serious burns and lost irreplaceable possessions in a unit fire Tuesday morning.
Noleen Madden, 61, and her live-in carer daughter Danielle, 22, are being supported by a network of friends and strangers trying to help ease the devastation the pair is facing.
Mrs Madden was found lying in her Claret St garage with her legs on fire about 9.30am Tuesday.
Ms Madden managed to fight the fire with a bucket and water before her mother was taken to Toowoomba Hospital in a serious condition with deep tissue trauma burns.
She was later airlifted to the Royal Brisbane Women's Hospital where she remains in a serious condition.
That is traumatic enough without having to face the utter destruction and ruins of a house fire which remains under investigation by authorities.
An online fund-raising page supporting Ms Madden and her terminally ill mother says the fire destroyed all photos, possessions and memories.
Queensland Fire and Emergency Services Inspector Peter Bradow said two fire investigators and two police forensic officers had as yet been unable to determine the cause of the fire.
It is believed the fire started in the main bedroom of the unit.
