We're fundraising for...
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

To the Brave Hearts of the Kosi Challenge In the shadow of the mountains high, Where Kosi’s peaks touch the sky, You gather with a noble aim, To fight a battle, to light a flame. With every step, with every stride, You carry hope, you walk with pride. For those who face the rarest fight, You bring a beacon, you bring the light. Through valleys deep and trails steep, Your courage wakes, your spirits leap. In unity, you find your strength, Together, you go to any length. For Rare Cancers, you stand tall, Answering the silent call. With hearts of gold and spirits true, The world is brighter because of you. So thank you, team, for all you do, For the lives you touch, for seeing it through. May your journey be filled with grace, And may you find joy in every place. Thank you for your incredible dedication and effort. Your participation in the Kosi Challenge is truly inspiring! 🌟(courtesy of Copilot et. al.)
