Reefsleep - Camping on the Great Barrier Reef!

Reefsleep recently launched and it allows you to spend two days and one night snorkeling on Hardy Reef. At night, you sleep on the upper deck of a pontoon floating on the reef-either under the stars in a hammock....or in air-conditioned tent with a king size. It is about 40 nautical miles from the shore. Okay, so it is a little more "glamping" (glamorous camping) than your average camping, but for an ocean-lover like me it sounds like an amazing experience.

The experiences include swimming, snorkelling, semi-sub rides, viewing fish from the underwater observatory, diving, and sunbathing. A night dive is also an option.

Okay, so its really high maintenance camping but I haven't heard of another opportunity like reefsleep. Are there any less "vacation"-like ocean/reef based experiences like this available? I've read a previous thread about how camping on water is very difficult so any hints or groups that do activities like this would be awesome!
