Community spirits were far from icy at Middle Harbour Public School, as the community gathered to support kindergarten parent Ron Hobden and raise funds for Motor Neurone Disease (MND) research.

Ron, parent of Lizzie and three-year old Henry, was diagnosed with MND two years ago, and there is still no cure.

Principal Laura Barry said the Big Freeze II event was as much about raising awareness as it was about raising funds.

“It’s a cause that's really close to our community's heart, because of Ron’s diagnosis two years ago,” she said.

“We're part of the fight with them and we want our students to see that it's really important to have the courage to stand up for, and beside others when they need it.”

To date, the school community has raised more than $13,000, which saw eight teachers taking a dunking in an ice bath, much to the delight of the students.

Surprise special guest, former Sydney Swans footballer Sam Reid, also took an ice bath.

Mrs Barry said she was incredibly proud of the community effort on display.

“Initially it was just to raise some funds and awareness, but what’s come about is this amazing sense of community.

“Parents have got involved organising the event and donating, and our teachers have readily put up their hands to be dunked in ice,” she said.

Mrs Barry said that if the community managed to raise $5,000, she would volunteer to be dunked.

The incredible fund raising saw her take three baths instead.
