After originally getting involved with the initiative to help raise money and awareness but a family members recent diagnose has seen Footy Colour Day make it's way to a special place in her heart. 

"Recently my 14-year-old cousin was diagnosed with bone cancer, he is currently undergoing chemotherapy," she said.

"Being an ambassador of Footy Colours Day and for a foundation that provides care, treatment and support for cancer patients and their families now holds a much more significant place in my heart," O'Dea said.

Footy Colours Day helps the Fight Cancer Foundation provide care, treatment and support for cancer patients and their families. Held during the month of September, people are encouraged to wear their favourite team’s colours and host an event at their school, organisation or club to raise funds for kids with cancer.

The campaign was established in 1995, where the funding went to help the Bone Marrow Donor Institute's programs, including the establishment of the Australian Bone Marrow Donor Registry.

Now the campaign helps to fund education support programs to address the gap in educational support for kids and young people living with cancer.

This will be O'Dea's second Footy Colours Day after being part of the 2017 campaign.

"(I'm) looking forward to putting on my Melbourne Footy Club colours and wearing them proudly," she said.
