A world-first marine discovery in Western Port Bay is reinforcing the region’s environmental significance and presenting a compelling opportunity for Council to champion local marine biodiversity.

Filmmakers Jack Breedon and Sheree Marris, who are documenting the bay, have captured the first-ever footage of the Swell Shark (Cephaloscyllium laticeps) exhibiting vivid green biofluorescence, a unique phenomenon never previously recorded in this species. Invisible under normal conditions, this hidden light display was revealed using specialised underwater lighting techniques.

The discovery, led by Western Port Down Under, a documentary and social impact initiative, is helping to reposition Western Port Bay as a marine environment of global interest.

Historically underrated, Western Port Bay is increasingly being recognised for its complex ecosystems and unique biodiversity. This discovery demonstrates that the bay supports previously undocumented marine behaviours and adaptations—reinforcing its value in both scientific and community contexts.

Council is working to develop a partnership with Western Port Down Under to raise awareness and build education resources to shift perceptions and increase awareness of Western Port’s marine life.

There is strong alignment between this initiative and Council’s objectives around environmental stewardship, community connection and regional identity.
