Swans stars, including Oncology Children's Foundation (OCF) ambassador Ryan O'Keefe, will be appearing on Sunrise on Monday 15 February, International Childhood Cancer Day.

Tune in at 8.45am to see your favourite players on-screen, as they remember Ben Clarke, who passed away two years ago at age seven, from childhood cancer.

On Monday, capital city cathedrals will 'Ring a Bell for Ben', honouring his life and raising awareness about the invaluable research into childhood cancer that OCF funds in Australia.

The Oncology Children's Foundation is the Official Charity Partner of the Sydney Swans. To learn more about the important work that OCF do, or to make a donation, visit www.ocf.com.au.
