Walter Brooksbank, a civil assistant to the Director of Naval Intelligence, worked in the 1920s and 1930s to organise a skeleton service of plantation owners and managers whose properties were in strategic locations in northern Australia, the Australian controlled

in a dugout canoe to search for survivors. The two scouts found the men after searching for five days. Lacking paper, Kennedy scratched a message on a coconut describing the plight and position of his crew; Gasa and Kumana then paddled through Japanese-held waters, at great personal risk, to deliver the message to Evans, who radioed the news to Kennedy's squadron commander. The future US president was rescued shortly afterward, and 20 years later welcomed Evans to the

"After the rescue Kennedy said he would meet us again," Kumana says in ''The Search for Kennedy's PT-109''. "When he became President, he invited us to visit him. But when we got to the airport, we were met by a clerk, who said we couldn't go—Biuku and I spoke no English. My feelings went for bad."
In July 2022, Coastwatchers James Burrowes and Ronald George Lee were still living, and were honoured in a wreath-laying ceremony by U.S. Ambassador to Australia Caroline Kennedy (daughter of President Kennedy) and General Mark Milley, Chairman of the U.S. Joint Chiefs of Staff.

In popular culture
There was an increase of interest in coastwatchers following the election of Kennedy to President in 1960. Coastwatcher characters appeared in films such as '' The Wackiest Ship in the Army'' and TV productions such as '' The Coastwatchers''.
