A young mother who was killed in a devastating house fire has been remembered as vibrant and kind, with beautiful soul.

Isabella Nicholls, 21, died in hospital in the aftermath of a blaze in a unit on Queensland’s Sunshine Coast.

Emergency services were called to an address on King Street in Buderim about 7.30pm on Sunday, where they found one of the units engulfed in flames.

Ms Nicholls, who was inside the property at the time, managed to escape the flames and was rushed to hospital.

But police confirmed on Monday that after being treated at the Royal Brisbane and Women’s Hospital for serious burns, she died as a result of her injuries.

On Monday evening, a fundraising page was set up in her memory and to support her grieving family.

“Despite the incredible efforts of the medical team, our precious girl passed away surrounded by loving family,” the page read.

“Isabella was a devoted and loving mother to her beautiful boy … who will now grow up without his mummy.

“She was also a much-loved daughter, sister, granddaughter, niece, cousin and friend.

“Our family is absolutely shattered by this unimaginable loss and the heartbreak is beyond words.”

The devastating blaze saw several neighbours evacuated from their homes, with police appealing for any witnesses to come forward with information.

Investigations are continuing into what caused the fire, which also saw a woman in her 30s assessed by paramedics.

Queensland Police Senior Sergeant Robert Lowry said investigations were at “a very early stage”.

“We have declared a crime scene. We’re speaking to people,” he told ABC.

“They are assisting us with our inquiries and we will continue that process and we’ll probably know more at the end of the day.

“The scene was quite confronting for all emergency services that attended and support is being provided.

“I also feel for the family of the deceased lady and I understand the family is also receiving support.”
