The most famous landmark in Australia’s northern oceans is the Great Barrier Reef. Running down much of the coastline of north eastern Australia, this World Heritage site is the world’s largest structure built by living organisms and is one of the few such structures visible from space.

At around 2 million litres, Sydney Aquarium’s Great Barrier Reef exhibit is the world’s largest, highlighting the enormous variety of life in this habitat.

Here you’ll see clown anemone fish dart amongst the waving tentacles of an anemone, sea stars and sea cucumbers silently creeping amongst the coral, wildly coloured triggerfish and vibrantly coloured tangs and angelfish zipping around then suddenly stopping in their tracks to be attended to by a tiny cleaner wrasse, deceptively beautiful lionfish hovering menacingly over coral formations in search of their next meal, brilliantly patterned lobsters waving their long antennae about and sleek tropical sharks seeming to move in time with the music.

By the time you reach the Reef Theatre, with its floor to ceiling window into the oceanarium and captivating music, you just will not want to leave!
