Calls for 'no-fishing' zone and new marine park around Mudjimba Island

Mudjimba Island, also known as Old Woman Island, is about two kilometres off the Sunshine Coast. (ABC Sunshine Coast)

A long-time mariner and diver is calling for a popular fishing spot to be eventually made off-limits to anglers, in an effort to protect thriving coral reefs and build fish stocks.

And he has the backing of a local politician.
