Friends and colleagues have paid tribute to John Holsinger, a mentor and legend in the fitness industry following a motorcycle crash.
The 70-year-old died after the vehicle he was riding left the road and caught alight 25 kilometres east of Broken Hill in far western New South Wales last Tuesday.
Mr Holsinger had been riding with a group of friends when he crashed, leaving him with serious head injuries.
He was flown to Royal Adelaide Hospital in a critical condition but died earlier this week.
'An inspiration'
According to many, he was a mentor and a leader with decades of experience in the fitness industry.
The Sydneysider was the Global Health and Fitness Association's (IHRSA) Asia-Pacific director since 2005.
His tireless work in the APAC region made our organisation stronger and the world a healthier place.
Mr Holsinger worked in the field across the world, with health leaders from China, Japan, India, New Zealand and a number of other countries.
One of his colleagues from China, Loni Wang, revealed: "John was an inspiration to me personally."
"John was a thought leader who led by example and was a true team player," friend and IHRSA vice president of international operations Alison O'kane Giannaras said.
"His wisdom and contributions will be deeply missed but not forgotten.
The 70-year-old is survived by his wife Val, and his family.
