As an ambassador, Ms Meek said she urged men to join Decembeard, a fundraising event in December.
"Bowel cancer claims the lives of 2200 Australian men annually and more than 8000 men will get the news each year that they have the disease," she said.
�Around 560 of those men who are diagnosed with it are under the age of 50 so it's really important for people to realise it's not just an older person's cancer.
"Awareness is crucial because it's estimated changes to diet " such as boosting dietary fibre intake, and reducing red meat and processed food consumption " could reduce the incidence of bowel cancer by up to 75 per cent."
Bowel Cancer Australia chief executive Julien Wiggins said he was looking forward to working with Ms Meek.
"We're delighted to have Julie join our team of high-profile ambassadors who have a lived-experience dealing with bowel cancer, either personally or through a loved one," Mr Wiggins said.
