Albanese Government Must Act: CSIRO Research Fuels Calls for Deep Sea Mining Moratorium

As the peak international body on deep sea mining begins a three-week meeting, CSIRO has released a series of reports commissioned by mining proponent The Metals Company (TMC) that underscore the severe environmental risks and scientific uncertainty surrounding the dangerous industry. The findings confirm international consensus; the deep ocean is too poorly understood to proceed with deep sea mining safely or responsibly, prompting major environmental organisations to call on the Albanese Government to support a moratorium.

The timing of the CSIRO reports appears to align with what was, until recently, TMC’s plan to submit an application to the ISA on June 27 – plans the company has now abandoned in favour of a controversial U.S. based pathway via a dormant 1980s law and enabled by the Trump administration. 

Pressure is mounting on the Albanese Government to adopt a precautionary stance supporting a moratorium at the ISA in line with many of its major partners, including the UK, Canada, France, Germany and New Zealand. Currently, 37 countries back a deep sea mining moratorium.

TMC continues to apply pressure on international regulators to accelerate approvals for this high-risk untested industry. With a state-funded agency producing research likely to be used to legitimise mining in international waters, ocean advocates are calling on the Albanese Government to direct CSIRO to take no further actions on behalf of TMC. 

The CSIRO reports confirm the likely damage to the seafloor and to the marine environment that civil society, Indigenous Pacific communities, and independent scientists have warned about; deep sea mining is too destructive and there is too much uncertainty to proceed. 

“These findings echo the concerns we’ve heard right across the Pacific region – that the deep ocean is a highly complex, precious environment, and that accelerating deep sea mining would be dangerous,” said Phil McCabe, Pacific Regional Coordinator at the Deep Sea Conservation Coalition.

There remains a severe lack of real-world data about deep sea ecosystems – particularly in relation to the long-term environmental impacts and the risk of toxic pollution entering the food chain. Scientists warn that many of these impacts are likely to be irreversible in human timeframes. The CSIRO reports acknowledge the potential for heavy metals to bioaccumulate in marine life, including tuna, swordfish, whales, and dolphins. 

“We’ve seen this before; traffic light systems, digital twin technology, adaptive management systems – all designed to give the illusion of sustainable management,” said Dr. Helen Rosenbaum, Research Coordinator at the Deep Sea Mining Campaign. “When the science is this uncertain, the only responsible signal is red.”

TMC’s recent decision to abandon its application to the ISA and instead issue permits through a dormant U.S. law has been widely condemned by governments and legal experts as a direct challenge to international law and multilateralism. The move undermines the ISA’s authority just as states prepare to negotiate key regulations.

“Australia’s credibility is on the line,” said Duncan Currie, International Lawyer and advisor to the Deep Sea Conservation Coalition. “CSIRO’s involvement with The Metals Company (TMC) risks implicating Australia in their attempt to sidestep international governance. The Albanese Government must now draw a clear line; support a moratorium at the International Seabed Authority, and ensure CSIRO takes no further action on TMC’s behalf.”

“At the ISA, a moratorium or precautionary pause on deep sea mining is the only viable path to protecting the deep sea,” said Shiva Gounden, Head of Pacific at Greenpeace Australia Pacific. “Delegates at the ISA must listen to the science and the voices of Pacific nations and back a moratorium to stop deep sea mining before it starts.”

The Deep Sea Mining Campaign, Deep Sea Conservation Coalition, Greenpeace Australia Pacific and Surfrider Australia call on the Albanese Government to announce its support for a Moratorium at the upcoming ISA meeting in Jamaica; and direct CSIRO to take no further actions on behalf of TMC.
