Across the Great Barrier Reef in Australia, spread across approximately 15-acre, the Pumpkin Island eco-resort is available for purchase. The island offers five cottage guests for accommodations that can populate up to 34 people. Among other things, you'll find two oceanfront bungalows, a licensed lounge, playground, gaming room, library, two-story lookout, and an administrator cottage. Furthermore, the island has two moorings, and it can be reached by helicopter or boat. There is the option to lease until 2046, with an arbitrary oyster lease. However, Pumpkin Island is a very discrete and private property, making it the best exclusive destination for entrepreneurs who can smell a good business opportunity.
