What you can do

Osprey Reef sits in the Coral Sea Marine Park — Australia's largest reserve, established 2018. GBR Marine Park is zoned no-take in Marine Park 'green zones'. The biggest pressure here is land-based runoff from Queensland farming — diving low-impact and supporting reef-restoration initiatives helps.

Protection status sourced from Protected Planet / WDPA and refined with Marine Protection Atlas. Fishing pressure proxy is Global Fishing Watch AIS data. See the methodology for what these sources can and can’t prove.
