Mark and Jay have been amazing supporters of HeartKids for many years. They are also one of our Sweetheart Day ambassadors.

Mark is from Dalby in Queensland and is a heart kid.  Jay is from Adelaide and they live together in Nashville, Tennessee where they produce their music as the dynamic duo O'SHEA and raise their gorgeous children.

Currently working on their 5th album for Sony Music Australia, they’ve won multiple Golden Guitar Awards (Australia’s CMAs) and hit #1 on the ARIA Country Sales Charts

They’ve performed everywhere from the Grand Ole Opry to the Sydney Opera House.

They have helped us promote HeartKids through their song Thank You Angels and more recently contributed to the Two Feet & A Heartbeat on-line Memorial Service. This Sweetheart Day, Mark will be telling his story to help raise awareness of CHD.

In the below video, you will listen to their story about how they have overcome congenital heart disease. With no cure in sight, they continue living with their passion, music, while raising awareness about the disease nationally and internationally.

Sweetheart Day

Sweetheart Day is HeartKids' annual flagship campaign. It is also widely recognised as International Congenital Heart Disease Awareness Month. The campaign is focused on Valentine’s Day (February 14), or for our community, International Congenital Heart Defect Awareness Day. 

Throughout February, HeartKids and CHD families will drive awareness about CHD and raise much-needed funds. 

Our focus is to expand our support for families and grow our services through our 1800 Helpline, parents education programs, family financial assistance, and in-hospital support initiatives, including our unique heart beads program.

HeartKids goal in 2021 is to increase access to our support services and programs across Australia, with a particular focus on those living in isolated communities.

HeartKids is Australia's only national charity dedicated to supporting those impacted by CHD and is a critical lifeline for thousands of Australian families. Funds raised from Sweetheart Day will go towards our support services and programs nationwide.
