In 2012, the Australian government under Labor/Kevin Rudd revealed plans to create the world's largest marine reserve network, made up of five main zones in offshore waters surrounding every state and territory. The number of marine reserves off the Australian coast would increase from 27 to 60 and would cover of ocean including the entire Coral Sea. The plans were met with criticism by commercial and recreational fishers, for being too restrictive, and by environment groups for skirting areas of potential oil and gasprospectively, and that just a small amount of the total area completely off-limits fishing.
Suspension and review
In the lead-up to the 2013 Australian federal election, the Liberal–National Coalition opposition led by Tony Abbott pledged to stop the expansion of marine protection parks announced during Labor's tenure. Following the election of the Abbott government in September, the reserves announced in 2012 were re-proclaimed new Commonwealth marine reserves, invalidating the management plans and exclusion zones before they came into effect the following year on July 1, 2014. As such, the suspension left the reserves as "paper parks" with no effective protection measures. A review into the 40 Commonwealth Marine Reserves that were announced in 2012 began in September 2014. This included the reserves of the South-west, North-west, North, Temperate East and Coral Sea marine regions. The results of the review were released in September 2016, which recommended zoning changes to 26 of 40 reserves and reductions to the area available to mining, while reducing the impact on commercial fisheries. A later release of draft management plans showed further reductions in no-take zones, including six of the largest marine parks that had the area of their Marine National Park Zones reduced by between 42% and 73%. The new management plans for the 40 marine parks came into effect on July 1, 2018, bringing all marine parks under protection.
Renaming
During a period of 2017, feedback was sought for the draft management plans of the 2012 Commonwealth Marine Reserves Review. The consultation process included a proposal to rename Commonwealth marine reserves. On 11 October 2017, the 58 Commonwealth Marine Reserves managed by Parks Australia were renamed as 'Marine Parks'.
Protection zones
Individual marine parks are assigned an IUCN category. However, each marine park may have one or multiple protection zones, each zone has an IUCN protected area category and related rules for managing activities to ensure the protection of marine habitats and species The following table is a summary of the zoning rules of Australian marine parks:
The Coral Sea Marine Park covers, it is the largest of Australia's marine parks and is located off the coast of Queensland in the Coral Sea.
Heard Island and McDonald Islands Marine Reserve
The Heard Island and McDonald Islands are located in the southern Indian Ocean, approximately 4,100 kilometres south-west of Perth, Western Australia. The marine reserve covers an area of approximately.
North Network
The North Marine Parks Network contains 8 marine parks covering, located off the coast of the Northern Territory and Queensland.
