The state government is resisting calls to make life jackets mandatory for all rock fishermen after another two fishermen drowned and says people must take responsibility for their own actions.

Two years ago a coronial inquiry into nine deaths recommended NSW bring in laws requiring a lifejacket to be worn while rock fishing.

150 rock fishermen have perished over the past 20 years.

But so far life jackets are only legally required in only one council, Randwick, where the law has been trialled since January. Fishermen in that council have been given a year's grace before they must pay a $100 fine if caught without a life jacket.

Surf Life Saving NSW is calling for those laws to be extended across the state.
