"It's incredible that I was smaller than a can of coke," Mr Heeley said.
Dr David Knight, director of Neonatology at the Mater Mother's Hospital, says Mr Heeley was a miracle baby.
He says only eight babies, weighing less than 400g, have been born at the hospital since 2000 and sadly only Mr Heeley has survived.
"The outlook for tiny premature babies is dependent on the weight and the gestation. Mr Heeley was very small for his gestation so he was relatively mature. I think that counted in his favour," Dr Knight said.
