An Australian television star is fundraising for the family living in her childhood home, which burnt down after lightning struck it earlier this week.

On Thursday, MasterChef 2019 winner Larissa Dominello launched a crowd-funding campaign for the family of seven living in her suburban Sydney home.

“Last night, I watched my childhood home burn down, the home of my grandmother and the home of my cousins,” she said on social media.

“The absolute devastation and loss I witnessed is something I’ll never be able to forget. We are so lucky that no one was injured or worse.”

The house, located in suburban Sydney, was the childhood home of Dominello’s grandmother and cousins.

Dominello said the tragedy rocked her.

“While during these times you’re reminded that material things don’t matter, losing absolutely everything you own is a unique kind of tragedy,” she said.

“Shout out to the amazing neighbours, volunteers, NSW RFS and NSW police who did everything they could to save this home.

“It’s pretty surreal knowing that all this devastation was caused by a strike of lightning and gone within hours.”

Over 70 firefighters battled the blaze, which destroyed the 10-bedroom property.

The 10-bedroom house in northwest Sydney was gutted by a fire on Wednesday night, believed to have been started by a lightning strike.

Eleven fire trucks and over 70 firefighters battled the blaze on Cattai Ridge Road in Glenorie, in Sydney’s Hills District.

The family home was fully engulfed, but the Zeaiter family who lived there managed to escape uninjured.

Dominello’s crowd-funding campaign has raised almost $15000 at the time of publication.

Matthew Lloyd from the NSW RFS told 9News the inferno forced crews out of the building “fairly quickly” before the roof collapsed.

“It was burning quite hot,” he said. “It was a fairly significant fire that extended throughout the roof cavity.

“So, unfortunately, despite the good work or the careers, it’s probably a total loss.”

At the time of publication, almost $15000 has been raised.
