Have you ever dreamed of floating in the middle of the ocean, above a coral garden beside a sand cay in a billowing reef home? Well here’s your chance, thanks to Airbnb. The home-sharing service is hosting a competition for four lucky people to stay overnight on a floating home in the middle of the Great Barrier Reef, all for free. The winners will be able to explore one of the world’s most impressive natural wonders with a private dive tour, and have meals cooked by celebrity Australian chef Neil Perry. He’ll be serving up a menu of local North Queensland produce, and that’s not all, guests will tour private coral gardens with a marine biologist. Enter the competition here by telling Airbnb about yourself, and why you belong on the Great Barrier Reef. Additionally, the company will be planting wetland plants for every guest visiting the region for the rest of the year.
