"[It] is clear that there are areas missing out on the protection they deserve, and we will be advocating for that to be improved through the process."
By comparison, the sanctuary zone within the Cape Byron marine park accounts for about a quarter of the park. For the Jervis Bay and Batemans marine parks, sanctuary zones are about a fifth of the total area.
'Holistic way'
Peter Steinberg, director of the Sydney Institute of Marine Science, also welcomed the Sydney marine park proposal, which forms part of the first stage of a 10-year Marine Estate Management Strategy.
“It’s a start," Professor Steinberg said. "It’s the first time that something like this has been attempted in this holistic way in the bioregion [taking in scientific, community, social and cultural values]."
The project took five years of "intensive work" involving scientists and a range of departments, he said.
Professor Steinberg, though, noted the $45.7 million set aside for the marine estate covers only the first two years of the strategy. Of that, $3.7 million will be spent on Sydney's marine park.
“I really do hope the state government is in it for the long term," Professor Steinberg said. "It’s a long-term approach to the coast so it’s really important resources be made available for that."
Sydney has about 600 species of fish alone, or as many as the entire UK, he said. “It’s a remarkably diverse place and really does warrant conservation and sustaining that biodiversity.”
'Sold short'
Labor and the Greens said they would push for changes to the plan.
"A network of protected sites does not a marine park make,” Penny Sharpe, Labor's environment spokeswoman, said.
"This long-delayed step towards some increased marine conservation is important but it sells the environment and our tourism sector short by failing to declare a marine park for Sydney," she said. "This is something Labor will do if elected in 2019."
Justin Field, the Greens marine spokesman, said: “The area of sanctuary protection falls well short of other marine parks in NSW at just 2.4 per cent of the region, but hopefully this represents a first step toward protecting marine life and coastal environments.
“More than 90 per cent of the NSW community, including fishers, support marine parks and sanctuaries - an investment in a healthier marine environment for all."
Professor Steinberg said the plan also recognised the need to adapt to climate change and its effects on Sydney's marine region.
"It's just as important to NSW as it is to the Great Barrier Reef," he said.
The overall marine estate strategy is "the first of its kind", Niall Blair, the Minister for Primary Industries, said. "It will streamline how we manage our 1750 km of coastline, 826 beaches and 185 estuaries in NSW."
Mr Field said the public should provide feedback to other protected regions under review.
“The NSW government is also currently reviewing marine parks and sanctuary areas at Solitary Island and Batemans Bay, and they should similarly maintain or increase protection at these sites,” he said.
