A fund-raising campaign to support search efforts for missing Tasmanian man Will Mainprize has raised more than $126,000.
Mr Mainprize was one of 43 crew onboard the livestock carrier Gulf Livestock 1 when it encountered a typhoon in Japanese waters last month.
Just three men have been found since the ship disappeared.
In other news:
One of them died shortly after their rescue.
To the frustration of the friends and families of the missing men, the search by the Japanese coast guard was scaled down to regular patrols on September 10.
Since September 14, a GoFundMe page has attracted $126,580 in donations as of Friday.
The funds so far have been used to pay for reconnaissance aircraft to scope uninhabited islands in the East China Sea at a cost of about $10,000 a day.
GoFundMe organiser and close friend of Mr Mainprize, Harry Morrison, said items such as a life raft capony, a life ring, and a single blue boot had been found after two weeks of searching.
"There are hundreds of uninhabited islets and islands in Japan that the crew could have been washed to and simply be waiting for us on," said Mr Morrison.
"This is not a search for closure, in our minds, this still remains an active search to rescue the missing crew.
"We cannot forget there are still four life rafts and one lifeboat from the ship still unaccounted for.
Anyone wishing to contribute to the GoFundMe campaign can do so by searching Save the Forty of Gulf Livestock 1.
