A young boy who suffered burns to almost his entire body has died following a house fire in Queensland's Darling Downs.
The four-year-old and his three-year-old brother were dragged outside by their father as their timber house at Weranga was completely destroyed around 7.30pm on Tuesday.
Three choppers landed at the rural property and ferried the family to Brisbane hospitals, but the four-year-old has since died.
His three-year-old brother is still fighting for his life in a critical condition in Lady Cilento Children's Hospital.
His 34-year-old father remains a stable condition in the Royal Brisbane Hospital.
"The two children, aged three and four, suffered 89 to 90 per cent burns to their whole body and the father suffered burns to his arms," Queensland Fire and Emergency Rescue spokesman Cameron Ashmore told the ABC earlier.
"The house is fully destroyed. Investigations revealed the house does not have smoke alarms so if smoke alarms were present, this might have been avoided."

It's believed the house did not have smoke alarms and all three were asleep when the fire started.
No one else was in the house at the time.
Fire investigators have started to comb the ruins to determine what caused the blaze.
