Swim Around Keppel is an open water swimming event held in the waters surrounding Great Keppel Island. The event offers various swimming formats, including individual, tandem, and team relay categories, with age requirements for each. Participation in the main individual event requires prior open water experience, and all individual swimmers must have an assisting vessel, while teams need a motorised support boat. Safety measures include support boats and personal watercraft stationed along the course, as well as course markers and buoys. The swim route follows the island’s coastline and is designed to take advantage of tidal movements.
