Floral tributes grow at scene after five children killed in Tasmania jumping castle tragedy identified

The Prime Minister will today visit the site where five children lost their lives in a horror jumping castle accident in Tasmania, as floral tributes blanket the scene where they died.

Zane Mellor, Jye Sheehan, Jalailah Jayne-Maree Jones, Peter Dodt, all aged 12, and 11-year-old Addison Stewart all died in the accident in Devonport on Thursday.

There were close to 40 grade five and six students taking part in the end-of-term activities at Hillcrest Primary School when the accident occurred.

Tasmania Police Commissioner Darren Hine said "the majority of those injured were in the jumping castle" when it was lifted by the gust of wind.

Three children are still fighting for their lives at the Royal Hobart Hospital, and one child was this morning discharged from hospital to recover at home.

Peter Dodt's sister expressed her pain after the death of her brother.

"It just hurts... knowing I won't be able to see him again," Peter's sister Chloe told 9News.

"We're not the only ones hurting, and we know that, it's horrible but thanks to those who are reaching out and helping," Jye Dodts, Peter's cousin, added.

The tight-knit community is mourning the loss of the children, saying it's a traumatic experience for everyone.

"No parent should have to go through this, nor should a family either," Felicity Miller told the Sydney Morning Herald.

Commissioner Hine said the whole Devonport region was feeling the loss deeply.

"Tasmanians are coming together to support each other at this very difficult time," said.

"Support those around you and ask for help if you are struggling."

Tributes for two of the children, Zane and Addison, have already been posted online.

Zane is being remembered as a "beautiful caring, gentle soul".

In an online fundraiser, a family remember of Addison wrote: "Everyone is devastated, she was always such a sweet kind, old soul."

Earlier, Prime Minister Scott Morrison expressed his "deepest sympathies" for the families involved.

"I want to extend on behalf of the government and Jenny and I, our deepest sympathies to all the families and all the community in Devonport for this horrific tragedy, that's occurred with the loss of five young precious lives, and more that hang in the balance," he said.

"Our first responders each and every day are trained to deal with some of the most unimaginable things, but on this occasion it goes beyond what they could have imagined."
