The Australian Defence Force said it found the men Sunday (Aug 2) on tiny Pikelot Island, about 190 kilometres from where they set sail three days earlier.
The men blew off course and ran out of fuel in a seven-metre (23-foot) skiff between two of the 600-plus islands and atolls that make up Micronesia.
Alerted by the Pacific Rescue and Coordination Centre in Guam, US and Australian military aircraft joined the search for the missing vessel and spotted their SOS message Sunday.
A helicopter dispatched from Australia’s HMAS Canberra flew to the island with food and water and found the three men in good condition.
A Micronesia patrol vessel was then sent to recover the men, the Australian Defence Force said.
