The state government is looking to change the Marine Parks Act 2007 that would see some relaxed restrictions on fishing in some marine parks and protections increased in other areas, as well as a new sanctuary zone created at Port Stanvac near Adelaide.
The government announced proposed changes to six marine parks.
Parks where some fishing would be permitted include St Francis Island in the Great Australian Bight, the North Neptune Islands south of Port Lincoln, Cooring Beach south in the South East, Cape du Couedic and the Clinton Wetlands.
Sanctuary zones at Nuyts Reef in the Bight and St Francis Island would also be expanded, creating an overall increase in marine environment protections.
Minister for Environment and Water David Speirs the proposal would sustain the economy as well as provide recreational opportunities and environmental protection.
"Creating jobs in regional communities and supporting livelihoods is a real priority for our state and we believe these changes support those communities doing it tough and provide appropriate protection for our marine environment," he said.
"The proposed changes would allow some fishing in areas where it has previously been banned but also see the expansion of other sanctuary zones to improve conservation outcomes.
"This is a win-win situation, conservation efforts would also improve with an overall increase in area protected by sanctuary zones."
Public consultation on the changes to the act opens on Friday May 29.
