Tasman Sea triumph: Australia’s Southern Bluefin Tuna fisheries secure MSC sustainability certification

Australia’s Southern Bluefin Tuna (SBT) longline and minorline fisheries have been independently certified to the globally renowned 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.

It demonstrates the fishery is world-leading in managing wildlife interactions and that the industry is committed to ocean stewardship.

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.

“This certification is a proud moment for the Australian tuna industry," said David Ellis, CEO, Tuna Australia.

"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, the Australian Fisheries Management Authority, and bio.inspecta."

The SBT fishery is notable for its selective fishing approach, originally using pole and line fishing methods to bespoke longline gear, significantly reducing environmental impact.

The industry has invested heavily in research, bycatch 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," said Anne Gabriel, MSC Oceania Program Director.

"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."

Why it matters:

• World-first MSC certification for Southern Bluefin Tuna longline
• Demonstrates that recovery is possible for highly valued species
• Builds global trust in sustainable fisheries through the MSC certification
• Generates economic benefits for rural and regional communities in Australia
• Opens new export opportunities for international markets
• Complements the recent MSC certification of purse seine SBT, providing assurance that all commercial SBT fishing in Australia is sustainable and well managed.

 “We’ve worked closely with the industry and our world-leading scientists to rebuild Southern Bluefin Tuna, which was once severely depleted through global over-fishing. This certification is evidence of responsible management, effective quota systems, and industry leadership," said Wez Norris, CEO, Australian Fisheries Management Authority.

“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," said Veronica Papacosta, CEO, Seafood Industry Australia.

“This recognition highlights the professionalism of Australian fishers and the robust governance of our Commonwealth fisheries. It’s a testament to how sustainability and profitability can go hand in hand," said Daniel Casement, Chair, Commonwealth Fisheries Association.
