MYSTERY ISLAND

.....is a part of Vanuatu.  However, googling the island is far more difficult.
It's 2km long, you are able to walk around it in 40 mins.  There is a grassed airstrip and an airport.  We were lead to believe it received the name Mystery Island in World War II.  That is all I]'m going to offer here as I fear it may be incorrect.  

A back blip.
