We're fundraising for... all people and patients affected by rare and less common cancers.
We are climbing for rare.
The Kosi Challenge is the single signature fundraiserfor 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 will be climbing with hundreds of others, in support of rare, in memory of and with those living with rare themself – together we are a community and Kosi unites us all!
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 – now we can get a ‘Kosi, Kosi, Kosi – Oi,Oi,Oi!’
P.S RCA is a Federal Government-classified Health Promotion Charity. All donations are fully tax deductible.
Thank you to our Sponsors
