I am fund-raising for my mum & dad who both had Cancer.

The Kosi Challenge is an annual event hosted by Rare Cancers Australia (RCA) to raise awareness and much-needed funds for Australians diagnosed with a rare, less common or complex cancer each year.

In March 2024, I will be climbing 2,228 metres above sea level to reach Australia’s highest point to help RCA.

One hundred per cent of funds raised through the Kosi Challenge goes towards the important work of RCA's Patient Support Team.

From helping patients to access specialists and treatments, through to delivering support groups, connecting people with services and providing financial assistance particularly in times of crisis, Patient Support is at the heart of what RCA does.

RCA is a Federal Government-classified Health Promotion Charity. All donations over AU $2 are fully tax deductible.

Thank you so much for your support.

My Updates

Raising awareness

Hi everyone,

I’m taking on a personal challenge to raise funds and awareness for Rare Cancers Australia, a charity that helps people with rare and less common cancers. These cancers account for half of all cancer deaths in Australia, but often receive less attention and research funding than more common types.

Rare Cancers Australia provides vital support and advocacy for patients and their families, as well as funding innovative research and clinical trials to find better treatments and cures. They also educate the public and health professionals about the challenges and needs of people living with rare cancers.

By sponsoring me, you will be making a difference for thousands of Australians who face a rare cancer diagnosis every year. You will also be helping me achieve my personal goal and challenge myself for a great cause.

Please visit my fundraising page here and make a donation today. Every dollar counts and no amount is too small. Together, we can make it fair for rare!

Thank you for your generosity and support.

Thank you to my Sponsors
