Why I'm Swimming as a Marilyn

Sunday 18th Jan
In 2020, my wife Kate was diagnosed with breast cancer and underwent surgery, radiotherapy, chemotherapy, and hormone therapy. After five years, we thought we'd put it behind us.
In 2025, Kate's cancer returned as metastatic disease.
This past year has been a relentless cycle of treatments, scans, and hospital appointments. Right now Kate is receiving 'Enhertu', a novel Antibody Drug Conjugate, that wouldn't be available without funding for cancer research and development.
This is why I'm putting on a platinum blonde wig and swimming as a Marilyn.
Cancer Council SA funds the research that gives patients like Kate access to these cancer medications. They support families navigating impossible decisions. They invest in finding better treatments and, hopefully one day, a cure.
Kate is fighting with everything she has and our children and I are doing everything we can to support her all while managing the daily reality of metastatic breast cancer.
Every dollar raised supports groundbreaking research, vital support services, and prevention programs that could spare other families from this journey.
I can't cure Kate's cancer, but I can swim (poorly). And together, we can raise funds and do our part to help treat/manage/end cancer.
Thank you for your support.
