More than 1,200 scientists urge rethink on Australia’s marine park plans
We, the undersigned scientists, are deeply concerned about the future of the Australian Marine Parks Network and the apparent abandoning of science-based policy by the Australian government.
On July 21, 2017, the Australian government released draft management plans that recommend how the Marine Parks Network should be managed. These plans are deeply flawed from a science perspective.
Of particular concern to scientists is the government’s proposal to significantly reduce high-level or “no-take” protection (Marine National Park Zone IUCN II), replacing it with partial protection (Habitat Protection Zone IUCN IV), the benefits of which are at best modest but more generally have been shown to be inadequate.

The 2012 expansion of Australia’s Marine Parks Network was a major step forward in the conservation of marine biodiversity, providing protection to habitats and ecological processes critical to marine life. However, there were flaws in the location of the parks and their planned protection levels, with barely 3% of the continental shelf, the area subject to greatest human use, afforded high-level protection status, and most of that of residual importance to biodiversity.
The government’s 2013 Review of the Australian Marine Parks Network had the potential to address these flaws and strengthen protection. However, the draft management plans have proposed severe reductions in high-level protection of almost 400,000 square kilometres – that is, 46% of the high-level protection in the marine parks established in 2012.
Commercial fishing would be allowed in 80% of the waters within the marine parks, including activities assessed by the government’s own risk assessments as incompatible with conservation. Recreational fishing would occur in 97% of Commonwealth waters up to 100km from the coast, ignoring the evidence documenting the negative impacts of recreational fishing on biodiversity outcomes.
Under the draft plans:
The replacement of high-level protection with partial protection is not supported by science. The government’s own economic analyses also indicate that such a reduction in protection offers little more than marginal economic benefits to a very small number of commercial fishery licence-holders.
This retrograde step by Australia’s government is a matter of both national and international significance. Australia has been a world leader in marine conservation for decades, beginning with the establishment of the Great Barrier Reef Marine Park in the 1970s and its expanded protection in 2004.
At a time when oceans are under increasing pressure from overexploitation, climate change, industrialisation, and plastics and other forms of pollution, building resilience through highly protected Marine National Park IUCN II Zones is well supported by decades of science. This research documents how high-level protection conserves biodiversity, enhances fisheries and assists ecosystem recovery, serving as essential reference areas against which areas that are subject to human activity can be compared to assess impact.
The establishment of a strong backbone of high-level protection within Marine National Park Zones throughout Australia’s Exclusive Economic Zone would be a scientifically based contribution to the protection of intact marine ecosystems globally. Such protection is consistent with the move by many countries, including Chile, France, Kiribati, New Zealand, Russia, the UK and US to establish very large no-take marine reserves. In stark contrast, the implementation of the government’s draft management plans would see Australia become the first nation to retreat on ocean protection.
Australia’s oceans are a global asset, spanning tropical, temperate and Antarctic waters. They support six of the seven known species of marine turtles and more than half of the world’s whale and dolphin species. Australia’s oceans are home to more than 20% of the world’s fish species and are a hotspot of marine endemism. By properly protecting them, Australia will be supporting the maintenance of our global ocean heritage.
The finalisation of the Marine Parks Network remains a remarkable opportunity for the Australian government to strengthen the levels of Marine National Park Zone IUCN II protection and to do so on the back of strong evidence. In contrast, implementation of the government’s retrograde draft management plans undermines ocean resilience and would allow damaging activities to proceed in the absence of proof of impact, ignoring the fact that a lack of evidence does not mean a lack of impact. These draft plans deny the science-based evidence.
We encourage the Australian government to increase the number and area of Marine National Park IUCN II Zones, building on the large body of science that supports such decision-making. This means achieving a target of at least 30% of each marine habitat in these zones, which is supported by Australian and international marine scientists and affirmed by the 2014 World Parks Congress in Sydney and the IUCN Members Assembly at the 2016 World Conservation Congress in Hawaii.
