2025 Ambassador: Trent Grimsey

Trent Grimsey is probably Australia's most outstanding Open Water Swimmer & we are delighted to have Trent as our Great Barrier Reef Ocean Swim Ambassador for 2025.

About Trent:

Trent Grimsey has recorded an impressive resume in only four years of competitive marathon swimming after making the switch from the pool in 2008.

At the 2009, Open Water Swimming World Championships in Italy, Trent placed second in the 25 km event. This was the first-time Trent had ever swum that distance. The pinnacle of his marathon swimming career was in 2012 with three FINA Open Water Swimming Grand Prix wins and one second place earning him the overall FINA Grand Prix Champion. This ranked him the number one marathon swimmer in the world - the first Australian male to win this title.

That same year, Trent became the fastest person to have ever swam the English Channel in a time of 6 hours and 55 minutes. Achieving everything he wanted to in the sport of marathon swimming Trent opted to retire on top in early 2013, at just 24 years of age. Known for his determination, work ethic and never say die attitude,

We are excited to announce Trent will be joining us on our 2025 swim!
