Triple world champions are few and far between. Teenaged ones rarer still. You can find one of them working in his parents’ plumbing supplies shop in suburban Sydney every Saturday morning when he’s not training, or six days a week in the off-season.
Liam Costello, 19, the slender and immaculately groomed young man who cleans the shop and fills orders for customers is the reigning, three-time Irish Dance world champion. He also has multiple All Ireland, North American and Australian championships under his belt. He won his third Irish Dance world championship in April in Belfast.
