Missing WA fisherman's bag found

A bag belonging to a crab fisherman has been found on the shore of WA's Pilbara coast, five days after he went missing.

There have been no sightings of Norman Leslie Bale, 52, despite extensive searches on Wednesday.

The dinghy he used was found on Tuesday near Dixon Island, about 20km from where he left.

He set off alone on Friday about 5pm from Back Beach boat ramp, 5km east of Karratha.

He has had no contact with family or friends since and was reported missing by a workmate at 7.30pm on Sunday.

The land search is continuing on Dixon Island and will extend into mangroves to the east of the island.

Search areas will be reviewed on Wednesday afternoon, when it will also be decided if searches will continue on Thursday.
