Australia’s southern bluefin tuna (SBT) longline and minorline fisheries have been independently certified to the Marine Stewardship Council (MSC)’s environmental standard for fishing, coinciding with the start of the SBT fishing season on 1 June.

The MSC assessment by the bio.inspecta team followed a rigorous, independent process that examined the fishery’s environmental impact, stock management, and monitoring against the science-based MSC standard.
This recognition places the SBT longline fishery among the world’s best-managed tuna fisheries and is a significant milestone for the Australian seafood sector.
It represents the world’s first MSC certification for longline SBT and complements the recent certification of purse seine SBT.
“This certification is a proud moment for the Australian tuna industry. Our members use low-impact longline fishing methods that reduce bycatch and protect marine ecosystems. Achieving MSC certification shows that our fishers are serious about sustainability and committed to leaving a healthy ocean for the next generation. The certification would not have been possible without the contribution and support from the Fisheries Research and Development Corporation and bio.inspecta,” Tuna Australia CEO David Ellis said.
The SBT fishery is noted for its selective fishing approach, originally using pole-and-line fishing methods to bespoke longline gear, which significantly reduces environmental impact. The industry has invested heavily in research, by-catch mitigation, and real-time monitoring to ensure responsible fishing practices.
“MSC certification shows that our Southern Bluefin Tuna longline fishery is committed to looking after the ocean and its wildlife. This isn’t just a label – it’s a way to celebrate the fishers who do the right thing, working responsibly and sustainably to protect marine life. By meeting these internationally recognised benchmarks, we are ensuring that Australian fishers can continue their vital work while safeguarding marine resources for generations to come,” MSC Oceania Programme Director Anne Gabriel said.
Seafood Industry Australia CEO Veronica Papacosta commented: “Australian seafood consumers both domestically and abroad are demanding proof of sustainability at an increasing rate. MSC certification provides global confidence that our seafood is responsibly sourced – it’s a win for the environment and for the economy.”
