The spritely senior discovered Masters’ swimming while recovering from a torn ligament, entering his first race in Woy Woy in 1999.
“I just fired off the blocks, had a really strong swim – and won the event,” Bill recalls.
“The adrenalin buzz was incredible, and I wanted to keep winning – so I found a swimming coach at the age of 70!
“It was the start of a whole new chapter in my life.”
Countless hours in the water have kept Bill agile in both body and mind, and while he admits he “loves food”, he works hard at keeping his weight down during competition season.
“I’m down to 72kg and I’ve learnt that the leaner you are, the fast you swim,” he says.
When asked for his secret to ageing well, Bill says the answer is simple: good DNA.
