The man's full identity was not immediately revealed until news of winning the Kosrae Nautilus Resort on the Micronesian island of Kosrae, which lies west of Hawaii and north of the Solomon Islands, had sunk in.
Joshua will take ownership of a resort, which is debt-free, profitable and has more than 20 years left on its lease.
Doug and Sally Beitz, who built the resort in 1994, have lived in Micronesia for more than two decades but said they felt it was time to return to Australia.

"Thanks for the awesome dream," wrote one ticket-buyer on Facebook. Another said: "Congrats Joshua, have a good life there."
