Kosi Challenge
DO Details
Join us for the 2026 Kosi Challenge!
Each year, teams and individuals take on Australia's highest peak, raising funds and awareness to support people livng with rare and less common cancers, every step of the way.
At Rare Cancers Australia, we do whatever it takes to ease the burden of a rare cancer diagnosis. Your support for the Kosi Challenge allows our Specialist Cancer Navigators to continue providing unique, personalised and limitless support for the big and small obstacles patients and their families can face.
Gather your friends, family or colleagues, register your team (or walk as an individual), and join us for an unforgettable weekend at Mt Kosciuszko.
