Port Bonython Introduction
Located on the western shore of the Spencer Gulf near Whyalla, Port Bonython is a site of significant economic and environmental importance. Historically known for its massive 2.4-kilometre-long jetty and as a processing facility for hydrocarbon liquids from the Cooper Basin, the area is currently transitioning into a global focal point for renewable energy. Future-focused developments aim to transform the precinct into a leading green hydrogen export hub, marking it as a key player in South Australia's transition to sustainable industry.
Beyond its industrial utility, Port Bonython is internationally famous for one of the world's most spectacular natural events. Every winter, thousands of Giant Australian Cuttlefish migrate to the shallow rocky reefs surrounding the nearby Point Lowly area to breed. This extraordinary 'migration of the giants' is the only known event of its scale globally, attracting divers, researchers, and nature enthusiasts who come to witness the cuttlefish's hypnotic, color-shifting displays in the clear coastal waters.
The area is also home to the historic Point Lowly Lighthouse, which has stood as a maritime sentinel since 1883. Visitors to the region can enjoy rugged camping sites, excellent fishing, and panoramic views of the Spencer Gulf against the backdrop of the distant Flinders Ranges. This blend of heavy industry, maritime heritage, and rare biological diversity makes Port Bonython a truly singular destination on the Eyre Peninsula.
