The search for a fisherman missing for the second time this month off the South Australian coast is set to resume.
Authorities launched a second search for the Margrel on Tuesday morning after the man on board, Tony Higgins, reported it was taking on water in rough seas off Granite Island, south of Adelaide.
About 500 square kilometres of coast has been searched so far but rough seas have hampered the efforts of authorities.
A wallet containing Mr Higgins' identification was found washed up on Goolwa Beach on Wednesday by a member of the public, along with other personal items.
A commercial fisherman earlier discovered a number of items of debris washed ashore several kilometres from the Murray Mouth.
Police will also scour the coast to see if anything else washes up, having already conducted land searches from Encounter Bay to Murray Mouth.
Mr Higgins, 57, and Derek Robinson, 48, were the subject of a major search south of Port Lincoln earlier this month after nothing was heard from the pair for several days.
The Margrel was eventually spotted off Coorong and towed to shore.
Mr Higgins was later fined $1000 for having insufficient safety equipment and no boat operator's licence.
He insisted at the time he didn't ask to be rescued and the pair "knew exactly where we were".
