David Glasheen, 65, who gave up the life of a businessman in Sydney to live the simple life on Australia's northern Restoration Island, wrote in his profile on dating site rsvp.com.au that he is "seeking a Girl Friday to make my island dreams come true," The Times of London reported Monday.
"One of the last true adventurers! Still looking for my mermaid," the bushy beard-wearing Glasheen wrote.
Glasheen holds a 50-year lease on one-third of Restoration Island and the remainder of the island is a national park. He said he has lived alone on his land for 12 years.
"There has to be someone out there for me," he told Sydney's Sunday Telegraph. "I've got an eye for the ladies, so I guess I would do anything to meet the right partner."
