THE GREAT BARRIER REEF
Tuesday we took a catamaran trip ~ 2 ½ hours from shore to the Great Barrier Reef. Thankfully, it was a large ship (with 150 passengers) so it didn’t rock much. That, plus a couple of ginger pills, kept Rosie from hanging over the bow “feeding the fishes”.
We took a “beach buggy” from the ship to the coral beach for snorkeling. The sand there is composed of ground up coral, thanks to the parrot fish that can each produce ~5 tons of coral sand each year. We were surprised to find that the sand really was not hot even under the mid-day sun.


The snorkeling was outstanding with lots of coral and fishes. Bob said he’s seen all those life-forms in the Philippines, just not in such quantity. I loved the florescent colors! We also saw a ray and several giant clams. We later took a semi-submersible ride where we took some photos. Unfortunately, the brilliant colors didn’t come through with those photos.

The reef is the largest living organism in the world, made up of thousands of species of corals. The corals are nocturnal, so we missed all the tentacle activity that goes on at night. There are both hard and soft corals with the soft ones waving in the breezes of the water currents. The reef covers an area larger than the state of Texas and its length is approximately equal to the distance from New York State to Florida. It’s also visible from outer space.
The coral cay (island) where we snorkeled is the most important bird breeding ground in the reef area. There were over 23,000 birds breeding there, an increase in population of over 22,000 in 4 weeks. The sooty tern (black and white) lays one sand looking egg on the beach and stands over it to shade it from the sun. These birds breed every 9-10 months.
There were many common noddy (brown) terns lined up on the beach “loafing”. These are the unmated birds that are “hanging out with their mates” in hopes of finding a real mate—kind of like hanging out in the pub. When they do mate, they build a bowl shaped nest in the grass using bits of coral. There were two crested terns nesting on the other side of the hill. We could only see their heads.
All of these birds spend the rest of their lives flying in the air, only coming to earth to reproduce. They have the ability to eat, and sleep in the air since one side of the brain shuts down at a time.
Wednesday morning we made a brief stop at the Tjapukai Aboriginal Park to learn about the northern aboriginal culture. We saw a film on the treatment of the aboriginals by the European settlers, another film about the dreamline, and a live performance of aboriginal dancing using a didgeridoo, wooden digging tools and boomerangs as musical instruments. The men’s bodies were painted with traditional nature designs. Although they had on clothing covering their bottoms, traditionally they would have only worn loin coverings usually made of hair.
Following a short bus ride from the Park to the Cairns’ Airport, it was time to say good-bye to the tropical area of Queensland and hop onto our airplane headed to Sydney where our journey will end in a few more days.
