'Fly High My Angel': Mother Of Teen Killed In House Fire Devastated By Loss

A teenager killed in a tragic house fire on the NSW Central Coast is being remembered as sweet, kind and gentle by family and friends.

Thirteen-year-old high school student Abby Hodge died after she was separated from her family in a raging house fire at Kincumber at about 12:30am on Wednesday morning.

Fire crews rushed to the scene to find the house fully ablaze.

Abby's parents, Rachel and David along with her 14-year-old brother and seven-year-old sister were found on the front lawn screaming for help, as they could not account for Abby.

Firefighters put their own safety to one side to do what they could to rescue the teen.

"This is a fire where firefighters would not normally enter the building," Inspector Rod Tabone from NSW Fire And Rescue said after the incident.

"When they heard there was a person inside there, they accepted that high level of risk," he said.

10 News First understands firefighters found Abby unconscious behind the door of a locked bathroom.

The crew brought her out of the house on a stretcher and commenced CPR until paramedics could take over, but sadly the teenager died on her way to Gosford Hospital.

On Wednesday morning Abby's devastated mother Rachel found the strength to post a short message on Facebook: "RIP my baby girl mummy and daddy love you so much fly high my angel."

School friends have also been left devastated by the sudden loss.

"She was kind to me, she just wasn't mean or anything, she was just a kind young girl," said year 8 classmate Tyler Martin.

Neighbour Lynette Cook lives in the house behind the family and told 10 News First she heard a loud explosion before looking out her window and seeing a "fireball coming from the house".

"The big explosion was just like a big bang and a big orange fireball which is why I thought there had been a car explosion," she said.

Lynette said her mother ran to try and help but the flames were too intense for anyone to get inside.

It's understood the fire started in the children’s rear bedroom, but the exact cause is still to be determined.

Early inquiries suggest the fire is not suspicious and was not a consequence of the storms that hit the Central Coast and Sydney Region on Tuesday night.

A crime scene has been established at the home and a full investigation is now underway.

A full report will also be prepared for the coroner.
