Just 6-days after Eli Spielvogel was born 13 years ago, he was rushed to the Royals Childrens Hospital with what's been described as a heart that looked like 'swiss cheese'.
After battling a long list of heart procedures, he now has a clean bill of health - and a full head of hair.
What started as a bet with his dad Adam (above) has grown into a unique way of paying it forward.., this time for the Leukaemia Foundation's Shave for a Cure...
After 3 years without a haircut, Eli will lose his lengthy locks at Damscas College on August 20.
