An environmentally friendly luxury resort built right on the beach, about an hour from Broome in WA’s Kimberley region, has been listed for sale for the first time since it was developed by entrepreneur Karl Plunkett.

Price expectations are above $25 million for Eco Beach Resort, which Mr Plunkett began building 26 years ago, when he discovered an idyllic fishing spot overlooking the Indian Ocean as a Kimberley tour guide.
