Life jackets may be made mandatory at WA's most deadly rock fishing sites, Premier Mark McGowan says.
Mr McGowan told reporters on Sunday the state government was looking at whether existing laws would allow for those not wearing a flotation device at fishing black spots to be fined.
"Some fishermen will not like that but we're trying to save lives," he said.
"If they're not doing it voluntarily, well, then a bit of enforcement might be needed."
The premier said the most notorious locations would be defined and a trial would be conducted first.
He said an obvious site would be Salmon Holes near Albany, where two men were swept off rocks on Saturday.
Police said they made their way onto a reef before being helped to the beach by bystanders who administered first aid while paramedics were called.
They were taken to Albany Hospital for treatment.
After holding inquests into the 2015 and 2016 deaths of three fishermen at Salmon Holes, a WA coroner recently recommended making life jackets mandatory at treacherous rock fishing spots.
The inquests heard a survey carried out in California revealed an extensive eduction campaign about wearing life jackets only increased their usage from nine per cent to 11 per cent.
But once it was made mandatory, regardless of policing, the percentage of people wearing life jackets rose to 70 per cent.
