Australia's Coral Sea

Beginning in 1972 I had the great good fortune to make twenty-nine ten-day cruises to the oceanic atolls of Australia’s Coral Sea. On a succession of live-aboards ranging from Coralita and Reef Explorer to Coral Princess, Hero and Elizabeth E I, we explored the Coral Sea paradises that lie far out to sea beyond the Great Barrier Reef.

In the 1970s and 80s we cruised from Rockhampton and Townville 300 miles across sometimes-bumpy seas to wondrous Marion Reef. During those decades, I was escorting groups of avid divers to many of the world’s richest coral reefs, but only the Sudanese reefs in the central Red Sea could approach the combination of stunning visibility, brilliant marine life and numbers of sharks that Marion Reef delivered year after year.

As the years went by, we explored other superb reefs in the Coral Sea such as Flinders, Diamond and Holmes before moving northward to dive the Cod Hole and Pixie Pinnacle on the Great Barrier Reef and North Horn and other sites on Osprey Reef.

Remarkably, each of these massive oceanic atolls had distinctive dive sites which differed radically from each other.

Marion Reef, for example, had dozens of skyscraper-sized coral towers rising up from the 200-foot depths of its lagoon to graze the limpid surface. Some of the most spectacular diving conditions I’ve ever seen occurred while soaring around these fabled pinnacles.

Diamond Reef had smaller pinnacles in the shallow areas of its lagoon, but its coral walls astounded us with vast arches, caverns and swim-throughs riddling the coral massif.

Holmes didn’t have much coral development in the shallows, but further down on its deep flanks there were soft coral colonies bigger than a diver, and in a rainbow of colors—pink, yellow, burgundy—which we always had trouble leaving. There was always just one more beautiful angle to be shot!

Osprey Reef was distinctive for a series of crevices in its outer wall which were swept by regular tidal currents. As a result of such rich and concentrated feeding, the walls were alive with hard corals, soft corals and sponges in varied colors—with night dives featuring hundreds of flashlight fish and huge nudibranchs.

In addition, one secret site had 20-foot trees of black coral and a wide meadow of huge soft coral trees stretching as far as we could see. Absolutely unforgettable!

The northern tips of both Marion Reef (“Action Point”) and Osprey Reef (“North Horn”) were home to healthy populations of hungry sharks. I learned a lot about what happens when sharks swarm to feed, and I’ll never forget some of those maelstroms of flashing and darting gray bodies.

On one memorable occasion, twenty or more gray sharks decided that I was to be lunch, and I only escaped The Final Chapter by bashing shark-noses with both big camera rigs until I could flatten myself against the coral wall. Memories, indeed…

These amazing reefs are protected only by 200-300 miles of open ocean, or they would be overrun with divers. As it is, only a fortunate few ever get to dive these remote wonders.

If you are a serious photographer, however—these are worth whatever it takes!...
