This gorgeous three-bedroom house is the ultimate in exclusivity: it sits entirely alone on Tasmania's east coast, with just the occasional passing white-bellied sea eagle for company. Rooms are decorated in a tasteful, minimalist style, but it's what's outside the house's glass walls that make Avalon Coastal Retreat truly dazzling: an infinite, unblemished expanse of white sand, blue sky and crashing waves that will leave your jaw hanging. At night, the house is enveloped in darkness and the sky resembles a planetarium. Every single thing a beach holiday maker could possibly need is provided: there's a kayak, surfboards and fishing supplies, a fully stocked fridge and kitchen, and helpful extras like a day pack and flashlights. You will want for absolutely nothing except more time to enjoy the stunning vistas.
