̊I am currently raising funds in support of my dear friend, Jareen Summerhill, who is courageously battling a rare form of cancer. Although she is no longer with us her unwavering strength and resilience serve as a constant source of inspiration for me.

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. I am firmly committed to providing assistance to others who find themselves in similar circumstances.

I firmly believe that by joining forces, we have the power to positively impact their lives and make a meaningful contribution towards their well-being. Together, let us make a difference in the lives of those facing these challenging situations.

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.

Jareen's warm virtual hug

Today, I want to share a deeply personal story about my dear friend, Jareen, who touched the lives of many before her untimely passing. It is with a heavy heart that I inform you of her battle with Cholangiocarcinoma, also known as Bile Duct Cancer.

Jareen was an extraordinary individual who exuded vitality and zest for life. Her accomplishments in both her career and personal life were nothing short of remarkable. She embraced every opportunity to explore different countries and cultures while emanating genuine compassion towards others.

Whenever I think of Jareen, memories flood back of her warm embraces that she generously shared with me, her family, and friends. However, fate dealt Jareen an unimaginable blow when she fell ill and sought medical attention to improve her condition. The diagnosis revealed the presence of an exceedingly rare form of cancer that posed significant challenges. Despite Jareen's valiant efforts to undergo treatment and explore potential clinical trials, her physical condition did not meet the initial requirements for these experimental treatments. Throughout this arduous journey, she maintained a positive outlook for the sake of her loved ones, but ultimately victory slipped through her grasp.

The loss of Jareen remains etched in our hearts even after the passage of time. Her infectious spirit and loving nature continue to inspire those who were fortunate enough to have known her. In honor of Jareen's memory and to support others facing Cholangiocarcinoma within Australia, I am committed to raising awareness and contributing to efforts aimed at combating this rare form of cancer.

I humbly request your support in joining me on this mission. By coming together as a community, we can make a difference in the lives of those affected by Cholangiocarcinoma. Whether it is through spreading awareness or supporting organizations dedicated to research and patient care, our collective effort can bring hope to individuals battling this devastating disease.

If you are interested in learning more or lending your support, please do not hesitate to reach out to me directly. Together, let us honor Jareen's memory by making a positive impact on the fight against Cholangiocarcinoma.

Together, we can triumph over this struggle by standing united.

I am deeply committed to supporting the cause of raising funds for cancer research in Australia. Personally, I have witnessed the impact this rare form of cancer has had on some close friends. They have chosen to keep their struggles hidden, fearing the limited time they have left with their loved ones. Experiencing such a devastating situation firsthand is truly heart-wrenching.

Providing unwavering support to individuals grappling with this challenge can make an immense difference in navigating this difficult journey. It fills me with great enthusiasm and gratitude to be involved in this initiative, standing alongside others in the fight against this terrible disease that afflicts patients who often face it alone.

By joining hands and actively participating in promoting and supporting this cause, we can help illuminate a path toward a brighter future for all those affected.
