The 11-year-old’s participation in the Krazy Kosci Klimb is showing what’s possible when you do your best.

Dubbed the “event with a difference” it provides a once-in-a-lifetime opportunity for people living with disabilities to reach Australia’s highest peak.

On Saturday Isaac’s determination will take him up and up as he climbs Mount Kosciuszko.

In his latest challenge, the Year 5 student has all of St Laurence’s Primary School willing him on.

A mural created by assistant principal Sharon Taylor depicts him at the summit.

It also carries caring messages of support from fellow students.

On Monday in the countdown to the climb, the school hosted a Zumba party, and collected donations to help the fifth Krazy Kosci Klimb towards its $300,000 target.

Ms Taylor told of Isaac’s impact.

“He’s very much an important part of our school community, not just in his own class, but among the other classes as well,” she said.

“We’re very blessed to have Isaac in our school community.”

The support from the school has been mirrored by the wider community, which has helped Isaac raise more than $6000 for the endeavour.

On Monday his parents, Michael and Anna Minney, showed their appreciation.

“We’ve had a few Bunnings barbecues, we’ve had a lot of people donate through the website, and then the school today is blowing us away,” Mrs Minney said.

“Thank you to everyone.”

The Krazy Kosci Klimb will be a family affair, with Isaac’s uncles Pete and Steve and cousin Eliza accompanying him and his parents.

Mrs Minney said Isaac would walk as much as he possibly could, and at other times use the jogging pram.

The funds raised will go to the Cerebral Palsy Alliance sports program, a cause the family is passionate about and more details are on the Krazy Kosci Klimb website.
