Fundraising update
Great work Friends with Altitude we have cracked the $3,000 mark already, incredible what a team of like minded people can achieve 👏We're fundraising for...
In March 2026, my amazing friends and I will take on the Kosi Challenge to raise funds and awareness for rare cancers - a cause that’s deeply personal to me. I’m currently living with a rare and incurable cancer, and like many others in this community, I’ve learned how little research and support these conditions often receive. Yet every rare diagnosis represents a real person, a real struggle, and a need for greater understanding.
Our team is climbing to help change that. By supporting our challenge, you’re helping to fund vital research and improve outcomes for people like me who are navigating diseases that often go unnoticed.
The Kosi Challenge is the single signature fundraiserfor Rare Cancers Australia (RCA), and all funds raised 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. RCA is a Federal Government-classified Health Promotion Charity. All donations over $2 are fully tax deductible.
Thank you for standing with us and helping create hope where it’s needed most. Now can I get a ‘Kosi, Kosi, Kosi – Oi,Oi,Oi!’
Thank you to our Sponsors
