The 43-year-old air rifle shooter, who made his debut when the Baltic isle last staged the event in 1999, will mark his tenth Games appearance with a leading role at the opening ceremony in Visby.
Described as a 'very popular choice' by Jersey's Island Games Association chairman Steve Jacobs, Turner is set to have over 220 athletes, coaches and officials behind him on 24 June – with Jersey's squad completed this week.
Gymnasts Elisha Stott (12) and Anushan Elanco (13) – Jersey's youngest competitors – have been confirmed as water carriers for the traditional Games water ceremony on the opening day.
'It's an amazing honour,' said Shetland 2005 and Rhodes 2007 air rifle team gold medallist Turner.
'Not many people get to do it. It's just one person out of a team of 230 every Games. The average competitive life of a lot of athletes in more active sports is two or three Games, maybe four if you're lucky. I'm lucky to have a prolonged competitive life being a shooter.
