Mel Gibson – Mago Island, $15 Million
In 2005, this actor shelled out $15 million to buy the Mago Island. Based in Fiji, he does not plan to put up resorts there since he simply wanted a private getaway. We are sure that it gets tiring to live in the middle of Hollywood craziness and be hounded by the paparazzi. This island boasts a gorgeous round shape. It spans 5,400 acres of amazing greenery. With a net worth of $450 million, this was pocket change for the actor. His work in Lethal Weapon 4 alone earned him $30 million!
