About the Kosi Challenge
Each March, we bring together the rare community to climb to the summit of Australia’s highest peak, Mt Kosciuszko for our major annual fundraiser.
The Kosi Challenge started with a small group back in 2013, and has now grown to run over two days. Hundreds of climbers join in-person at Thredbo, alongside virtual climbers who take on the challenge from anywhere in Australia or even around the world!
Kosi unites people from across Australia, including patients and their families, industry, businesses, community groups and more. It raises much-needed funds and awareness for people in Australia affected by rare, less common and complex cancers.
No one should have to go through their cancer journey alone. That’s why we walk the journey with those impacted.
