IN the sun-drenched suburb of Blacksmiths, everyone knows the name Lily Costello.
The 14-year-old St Mary's High School student belongs to Catherine Hill Bay Surf Life Saving Club and is well known in her community.
From nippers to national titles, Lily moved up through the surf lifesaving ranks, hot on the heels of older brother Isak, from the Redhead club.
At age nine, she entered her first state competition and returned home with three gold medals for swim team, board team and individual events.
At the national championship in North Kirra last year, Lily was second in the ironman race and sixth in the board team event.
She started the competitive surf season strongly this year at the Stockton Carnival in October, where she won the ironman and board races.
Last month, Lily was selected by Hunter Surf Lifesaving for the 2013 representative team to compete at the NSW Interbranch Championship at Soldiers Beach from December 14-15.
Lily said she loved surf lifesaving and hoped her skills would take her far.
"I love being at the beach and competing, and I also get to travel a lot, which is great," she said.
"One day I hope to make the Nutri-Grain championships and be crowned ironwoman."
