A critical once-in-a-decade review of Commonwealth marine parks is currently underway, prompting an urgent response from the scientific community. Nearly 300 of the world’s leading marine scientists Australia has produced, including prominent researchers from The University of Western Australia, have united behind a scientific consensus statement. Their objective is clear: secure a resilient future for the nation’s oceans by significantly expanding highly protected marine parks and removing industrial extractive activities from these vital ecosystems. This unified call to action represents a pivotal moment for Australia marine conservation, urging the Federal Government to align its policies with contemporary scientific evidence.
Understanding the Current State of Australia Marine Conservation
Australia manages one of the largest marine jurisdictions on the planet, yet the distribution of its protections reveals a significant spatial mismatch. While the nation boasts that roughly one-quarter of Commonwealth waters fall under some form of high protection, this statistic masks a critical flaw. When examining the waters immediately surrounding mainland Australia, that protection drops dramatically to just 9.6 percent.
Currently, the majority of highly protected sanctuary zones are concentrated in remote offshore areas and territorial waters. Meanwhile, the coastal regions—where biodiversity is richest, human pressures are greatest, and productive marine ecosystems thrive—remain largely under-protected. This imbalance leaves the most ecologically significant areas vulnerable to degradation. As oceans face escalating threats from marine heatwaves, habitat loss, pollution, and expanding industrial use, maintaining the status quo is no longer a viable strategy for ocean protection Australia.

The Critical Role of Highly Protected Marine Parks
To understand the scientists’ demands, one must differentiate between partially protected areas and highly protected marine parks. Partially protected areas often allow various levels of extractive activity, which diminishes their ecological value. In contrast, highly protected zones (classified as IUCN Ia or II) function as no-take sanctuary zones where all industrial extraction is prohibited.
Decades of empirical research demonstrate that these strict sanctuary zones deliver substantially stronger outcomes for biodiversity, fisheries, and overall ecosystem resilience compared to their partially protected counterparts. Without strict regulations, marine parks risk becoming “paper parks”—areas that exist on maps but fail to provide real-world conservation outcomes due to inadequate enforcement and ongoing extractive practices.
Eliminating Destructive Industrial Activities
A primary concern highlighted by the scientific consensus is the continued permitting of destructive practices within marine park boundaries. Bottom trawling, longlining, and seabed mining are currently allowed across approximately one-third of mainland Commonwealth marine parks. Bottom trawling, in particular, devastates benthic (seafloor) habitats, destroying complex ecosystems that take decades or even centuries to recover. Removing these industrial activities from all marine parks is a non-negotiable step toward genuine Australia marine conservation.
Restoring Fish Stocks and Building Climate Resilience
Dr. Enric Sala, Explorer-in-Residence at the National Geographic Society and a co-author of the statement, notes that fully protected marine reserves are the most effective tool for restoring ocean health. These sanctuaries not only protect resident species but also serve as biological reservoirs. Fish populations within no-take zones grow larger and more abundant, leading to a “spillover” effect that replenishes nearby fisheries. Furthermore, highly protected ecosystems demonstrate greater resilience to climate change, buffering the impacts of warming waters and acidification.
Five Key Actions Demanded by Marine Scientists Australia
The consensus statement outlines a structured, actionable framework for the Federal Government. To secure the future of its marine environments, marine scientists Australia are calling for the implementation of five specific policies:
- Protect 30 Percent of Each Bioregion: Commit to protecting at least 30 percent of every Australian marine bioregion within highly protected no-take sanctuary zones, with immediate priority given to the under-protected waters around mainland Australia.
- Prevent Downgrading: Formally commit to halting any future downgrading, downsizing, or de-gazettement of existing highly protected marine park zones to prevent backsliding on conservation gains.
- Remove Industrial Extraction: Legislate the removal of industrial extractive activities, including bottom trawling, longlining, and mining, from all marine park boundaries.
- Adequately Resource Management: Provide sufficient funding for marine park management, enforcement, monitoring, and research. This ensures parks are actively managed rather than existing as ineffective “paper parks.”
- Invest in Education and Indigenous Engagement: Fund national communications to improve public understanding of ocean stewardship and foster meaningful engagement with Indigenous custodians, who have managed these waters sustainably for millennia.

The University of Western Australia’s Leadership in Marine Science
The push for stronger marine protections is heavily supported by leading academic institutions, most notably The University of Western Australia. Professor Jessica Meeuwig AM, the Wen Family Chair in Conservation at UWA and a co-author of the consensus statement, has been at the forefront of this research. Her work, alongside the UWA Marine Futures Lab, continues to provide critical data on the health of marine ecosystems, such as the Eastern Recherche Marine Park and the Bremer Marine Park.
Professor Meeuwig emphasizes that Australia has already built a strong foundation for marine conservation, but the current review presents a rare opportunity to correct existing spatial imbalances. By prioritizing areas where human pressures and biodiversity intersect, UWA’s research directly informs the policies needed to achieve lasting ocean protection Australia. The institution not only contributes high-level scientific evidence but also trains the next generation of ocean scientists who will continue this vital work.

Shaping the Next Decade of Ocean Protection Australia
The Federal Government’s ten-year review represents a defining juncture. The decisions made in the coming months will dictate the health and productivity of Australia’s oceans for the next generation. The scientific community has provided a clear, evidence-based roadmap. Implementing the proposed five actions would elevate Australia from a nation with a fragmented marine park network to a global leader in Australia marine conservation.
Stepping up strict protections now allows Australia to demonstrate the bold leadership required to secure a thriving marine planet. By expanding highly protected marine parks, eliminating destructive extractive practices, and adequately funding enforcement, the government can ensure that its waters remain resilient in the face of unprecedented global environmental changes. The consensus among marine scientists Australia is unanimous: the time for incremental change has passed, and comprehensive action is urgently required.
