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.
