Australia plans huge marine reserve in Coral Sea
Environment Minister Tony Burke said the protected zone would cover an area more than one-and-a-half times the size of France.
New fishing limits would be imposed and and exploration for oil and gas banned.
The proposal is subject to a 90-day consultation, but Mr Burke said the Coral Sea's biodiversity was at the heart of the plan.
"There is no other part of Australia's territory where so much comes together - pristine oceans, magnificent coral, a military history which has helped define us and now a clear proposal for permanent protection," he said.
The sea - off the Queensland coast in north-east Australia - is home to sharks and tuna, isolated tropical reefs and deep sea canyons. It is also the resting place of three US navy ships sunk in the Battle of the Coral Sea in 1942; Kazinform cites BBC.
