275 Marine Scientists Call for Urgent Overhaul of Australia’s Marine Park Protections

As the Australian Federal Government embarks on its once-in-a-decade review of the nation’s Commonwealth marine parks, a powerful coalition of 275 marine researchers—ranging from foundational experts to emerging leaders in the field—has issued a stark call to action. Their consensus statement, titled Securing a Resilient Future for Australia’s Oceans, argues that current management practices are insufficient to safeguard the health and future of the country’s vast maritime estate.

The core of the scientists’ concern lies in a significant discrepancy between current protections and modern conservation standards. While the total percentage of Commonwealth waters under protection may seem substantial, the experts point out that less than 10 percent of Commonwealth waters surrounding mainland Australia currently reside in high-protection sanctuary zones. This, they argue, falls well short of the scientific benchmarks required to foster resilient, healthy ecosystems.

The Case for Stricter Sanctuary Zones

Professor Jessica Meeuwig AM, Wen Family Chair in Conservation at The University of Western Australia, emphasized that this review represents a critical juncture for the nation’s environment.

“Australia has built a strong foundation for marine conservation, and this review is an opportunity to build on that success,” Professor Meeuwig said. “However, the science clearly shows we need stronger protection where biodiversity, fisheries, and human pressures are greatest.”

Professor Meeuwig highlighted a geographic imbalance: while about one-quarter of all Commonwealth waters are highly protected, that figure plummets to just 9.6 percent when focusing on the mainland. Furthermore, industrial activities such as mining and bottom trawling remain permitted across roughly one-third of mainland Commonwealth marine parks, a practice the group believes is incompatible with modern ocean stewardship.

Aligning Policy with Global Science

The coalition is urging the government to adopt five specific pillars of reform to modernize the management of these vital areas. These include:

• Expanded Protections: Ensuring at least 30 percent of every Australian marine bioregion is covered by highly protected “no-take” sanctuary zones, with an immediate focus on mainland waters.
• Irrevocable Status: A commitment to prevent the future downgrading, downsizing, or de-gazettement of existing high-protection areas.
• Industrial Phase-out: The removal of extractive industrial practices, including longlining, trawling, and mining, from all marine parks.
• Operational Integrity: Adequate funding for monitoring, management, and enforcement to ensure that protected areas do not become ineffective “paper parks.”
• Public and Indigenous Engagement: Increased investment in national education and communication initiatives to foster better public understanding of marine stewardship.

Associate Professor Carissa Klein, Director of the Centre for Biodiversity and Conservation Science at the University of Queensland, noted that the benefits of such policies are well-documented. “Decades of scientific evidence show that highly protected sanctuary zones deliver substantially stronger biodiversity, fisheries, ecosystem, and climate resilience outcomes than partially protected areas,” she explained.

A Global Benchmark for Leadership

The call for reform has gained international backing as well. Dr. Enric Sala, founder of the National Geographic Society’s Pristine Seas initiative, described fully protected marine reserves as the most effective instrument for restoring ocean health and mitigating the impacts of climate change.

“By stepping up strict protections now, Australia can demonstrate the bold leadership the world needs to secure a thriving planet for generations to come,” Dr. Sala stated.

As the Federal Government evaluates the future of its marine parks, the consensus from the scientific community is clear: the status quo is no longer enough to buffer these ecosystems against the mounting pressures of marine heatwaves, pollution, and habitat loss. For the 275 signatories, the upcoming policy decisions are not merely bureaucratic, but essential to the survival of Australia’s underwater heritage.
