We are climbing for rare.
The Kosi Challenge is the single signature fundraiser for Rare Cancers Australia (RCA), with the sole purpose of raising awareness and much needed funds for people across Australia impacted by rare and less common cancers.
In March 2026, we (Ol, Mads, Barns, Tony, Caroline, Rob and Ted) will be climbing Kosi in person with hundreds of others, as well as racking-up kms virtually in Melbourne and New York!
All In support of rare.
All funds raised through the Kosi Challenge goes directly towards funding the individualised, 360 degree person centred support that RCA’s team of specialist cancer navigators provide for patients, carers and their families.
Thank you so much for your support!
P.S RCA is a Federal Government-classified Health Promotion Charity. All donations are fully tax deductible.
