The Great Barrier Reef is one of the seven natural wonders of the world and one of the main reasons to visit Australia. It’s the same length from Vancouver to the Mexican border, consisting of 900 islands and 2,900 individual reefs.
Sounds lovely, right? But it’s also expensive. Not only because it’s more luxurious but because most private boat charters can only be rented for week-long cruises (they need to make it worth their while).
