This page has been created to share the story of Dr Barnes, the history of the boardwalk that bears his name, and the unique environmental values of the surrounding mangrove ecosystem. Historical documents, photographs and additional resources will continue to be added over time.



About Dr Jack Barnes

Dr Jack Barnes (1922-1985)

Doctor • Naturalist • Pioneer Jellyfish Researcher

"There's no such thing as I can't, but it's okay to say I tried and I couldn't."

Born in south-west Queensland, Jack Barnes developed a lifelong connection with Far North Queensland, its people and its natural environment. His curiosity and determination led him to become one of Australia's most influential marine researchers.

Working alongside lifesavers and the wider community, Dr Barnes undertook pioneering research into dangerous marine stingers. His work on the box jellyfish (Chironex fleckeri) significantly improved understanding of the species and helped make the region's beaches safer.

Dr Barnes is perhaps best known for solving the mystery of Irukandji Syndrome, demonstrating that the condition was caused by a tiny, almost invisible jellyfish. In recognition of his groundbreaking research, the species was later named Carukia barnesi in his honour.

Today, the boardwalk stands as a tribute to Dr Barnes' lasting contribution to science, conservation and the Far North Queensland community, while also celebrating the unique mangrove environment he helped inspire others to appreciate.
