Waiting to own something huge and expensive??? Here is your choice

It's Vatu Vara (above and below), in Fiji.
"Reputed to be the most expensive island in the world.
Vatu Vara Island lies in the northwest sector of Fiji's northern Lau Group of islands, 32km west of Mago Island and some 60 km south-west of Vanua Balavu at Lat: 17° 26'00 S Long: 179° 31'00 W. Vatu Vara is often referred to as 'Hat Island' because of its unusual shape.
Its limestone cliffs are covered in dense tropical jungle and the flat summit is like a cross between Bora Bora and 'The Lost World' of Sir Arthur Conan Doyle. And Mel Gibson is a neighbor: he owns Mago Island, just 32km east.

It is a former atoll, specifically called a “Guyot”. This is an extinct volcano that has become overgrown by coral reefs to form an atoll. The flat top was once at sea level, which is why the summit is flat. Its unmistakable shape, and its massive peak like that of a vast stone hat, dominates the surrounding skyline and is recognizable over a radius of thirty-five miles (56km) from nearby islands such as Kaibu, Yacata, and Vanua Balavu.
