Get a swim team together at your gym and raise money for the Children’s Cancer Institute.

The Balmoral Swim  is a unique open water swim held within the beauty of Sydney Harbour, making it a safe event for all. Whether you are a seasoned veteran or a newcomer to ocean swimming, we have an swim option for you.

The event is in it’s 30th year and is organised by volunteers, most of whom are members of the Balmoral Beach Club. However the entire local community get behind the event to make it happen. From Mosman Council, to HMAS Penguin, to the Balmoral Sea Scouts, all are supported by our sponsors;  Gold – Audi Mosman, Dexus & URM, Silver – Jeckra & Medilab, Bronze – Edney Ryan and

Community engagement continues to grow. This year internationally acclaimed artist Ken Done has designed swimsuits which capture the unique Balmoral landscape, and Mosman Men’s shed has constructed the winners podium. We will also have a fun selfie wall to help all competitors spread the word about the work of the Children’s Cancer Institute.

The Balmoral Swim has raised more than $1,000,000, since 1990 and this year hopes to raise $350,000.

The Children’s Cancer Institute is the only independent medical research institute in Australia wholly dedicated to childhood cancer and every dollar received from the government and granting bodies to support direct research costs must be matched with a dollar raised by the community.

Children’s Cancer Institute’s Executive Director, Prof Michelle Haber said:

“By holding this event the Balmoral Swim is helping us undertake the medical research we know will uncover a cure for childhood cancer. Fundraising events like the Balmoral Swim enable us to continue this critical research – and demonstrate what can be achieved when communities unite for a common cause.”

This year all funds will go toward the Zero Childhood Cancer program. The most exciting childhood cancer research initiative ever undertaken in Australia. This world-class program brings together all major Australian clinical and research groups working in childhood cancer to offer Australia’s first ever personalised medicine program for children with high-risk or relapsed cancer.
