A 45-year-old firefighter with life-threatening burns remained in a critical condition in hospital last night while her 24-year-old colleague was stable.
The Department of Environment and Conservation firefighters were injured after they were engulfed in flames near Albany on Friday.
They became trapped in the path of the fire after strong winds quickly changed direction as they fought a blaze on a private property near Two Peoples Bay.
Friends and relatives of the women have asked people to pray for them as they fight to survive their extensive injuries.
The 45-year-old suffered burns to 60 per cent of her body and her colleague had burns to about 20 per cent. A sister of one of the firefighters posted on Facebook: "They are brave women and fighters, God bless them."
The women had been with about 20 other firefighters when they were injured about 3pm.
Four other men in the group, who included DEC and volunteer firefighters, were treated at Albany Hospital for minor burns and smoke inhalation. They have since all been released.
Firefighters brought the fire under control yesterday.
WA Volunteer Bushfires Association president Terry Hunter said all those involved had been offered counselling.The cause of the fire, which burnt through 1500ha, was not known.
