Mysterious Montgomery reef - now you see it, now you don't.

One of the highlights of my West Australian cruise on Oceanic Discoverer. A vast reef, appearing as if by magic out of the ocean on a falling tide, is a marvellous and most unexpected sight.

I'm sitting in an inflatable landing craft, about 20 km off the Central Kimberley coast.  As far as the eye can see, there is water cascading off an endless wall of rocky coral.  Due to extreme tides in this area, the reef literally "grows" in front of my eyes as water pours off in a thousand rivulets down a multitude of crevices.

 

In a few hours when the tide comes in, there will be no trace of any reef, no coral, no rocks. Just a vast expanse of ocean. The show will be over until Nature puts on an encore with the next falling tide.

This astonishing mass of rock is the largest inshore reef in Australia, being an incredible 80km long.  It covers an area of over 270 square kilometres. By comparison, this is roughly the same area as Taipei City in Taiwan, home to over two million people... Montgomery Reef, home to zero people.

Montgomery Reef was named after Andrew Montgomery. He was ship's surgeon on HMS Mermaid, captained by explorer Phillip Parker King in 1821.
Definitely worth seeing if you can get out here. The "full Monty" is an incredible spectacle to behold.
