Jellyfish Nets

Protect swimmers from jellies by providing netted bathing areas.


Our jellyfish nets are primarily used at public, private and hotel beaches to protect swimmers from jellyfish within a confined area. They also perform a similar role (or may form part) of a swimming barrier to demarcate a safe swimming area or a debris boom to protect a swimming area from rubbish.

Our Jellyfish Nets are (custom) made for each project, and designed for quick and easy maintenance, repositioning, re-installation or removal.

The nets can be supplied as a stand-alone barrier or detachable barrier that can be attached to an existing swimming barrier, and do not harm marine life.
