We're fundraising for...Patients

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 2025, we 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.

Thank you to our Sponsors

Kaid is the most honourable and symmetrical man I have ever met. Kind, caring, intelligent and selfless, he's the man I wish I could be. Truely an inspiration. Treasure him and treat him well, because any company would be lucky to have him and every company would be distraught if they lost him. Irreplaceable and heaven sent.
