For 500,000 Australian children and their families, every day is spent in unbearable suspense, not knowing what tomorrow will bring. Project Y aims to put an end to this uncertainty by providing much-needed answers to children with a rare or undiagnosed disease. To make this happen, we need your help!

Arj Barker is helping to solve the most challenging medical mysteries for children, just by telling a joke. You can help us raise awareness by sharing the joke on your social media pages.
