The mother of three was asleep in her Fairy Meadow home in Wollongong’s north when the fire erupted about 2am, turning the house into a raging inferno.
While enroute, fire crews were given “critical information” about the exact location of the woman trapped inside the burning house, according to a NSW Fire and Rescue statement.
Multiple fire crews attended the scene, the statement said.
“We had firefighters jumping through windows in an attempt to save life,” Chad Wallace from NSW Fire and Rescue said.
“Extremely intense fire conditions with flames bursting out of every window and thick black smoke coming out of every space in the house.”
Four other occupants of the house including her sister and three children managed to escape injury-free before firefighters and emergency services arrived.
The 33-year-old remained on the phone to firefighters as they attempted to locate her inside the burning house.
After being pulled from the blaze, the woman went into cardiac arrest with paramedics conducting CPR to keep her alive.
She was then taken to Wollongong Hospital in a critical condition.
Officials have launched an investigation into the cause of the fire however at this stage it is believed to be an accident.
