I am fundraising for..

The Kosi Challenge is an annual event hosted by Rare Cancers Australia (RCA) to raise awareness and much-needed funds for Australians diagnosed with a rare, less common or complex cancer each year.

In March 2024, I will be climbing 2,228 metres above sea level to reach Australia’s highest point to help RCA.

One hundred per cent of funds raised through the Kosi Challenge goes towards the important work of RCA's Patient Support Team.

From helping patients to access specialists and treatments, through to delivering support groups, connecting people with services and providing financial assistance particularly in times of crisis, Patient Support is at the heart of what RCA does.

RCA is a Federal Government-classified Health Promotion Charity. All donations over AU $2 are fully tax deductible.

Thank you so much for your support.

Well done Lindy.

Thank you Lindy for your support during my treatment journey. You and the team are always happy, encouraging and supportive. You have all taken on a very personal challenge to raise funds and undertake the Kosi Challenge while still working and caring for your patients during the Chemo cycles. With help from you and the team I have achieved another reduction in CEA Tumour Markers . between 2 Jan and 15 Jan when they fell from 7.9 to 7.6. Thankyou.
