Tanned 20-somethings frolicking barefoot are not the first thing that enter most people's minds when they hear the words lawn bowls.
The sport is most commonly associated with pristine white uniforms worn by grey-haired players and a conservative code of conduct.
But lawn bowls is undergoing a youthful transformation in Australia, as the country's 2,000 bowling clubs relax rules on membership and dress code to appeal to a new generation.
Barefoot bowls came into being over a decade ago and the sport's popularity has been on the rise ever since.
Patrick Henningham is an instructor at Paddington Bowls club in Sydney's Eastern Suburbs.
He spoke to BBC News about the appeal of barefoot bowls and gave a quick guide to how the game is played.
