The Great Barrier Reef
Cairns
Like
Uluru Kata Tjuta National Park the Great Barrier Reef is one of those
must-see locations in Australia. After a pretty cold winter in Canberra
we decided to take a few days and warm up in the northern part of
Australia.
Although most of our holidays involve camping we only had a few days
and decided to fly up to Cairns and stay in
a Resort... a first for me! I'm not really one for organised
tours but the package put together by Reef Magic cruises look
pretty attractive. Having undertaken the Train trip to Kuranda we were
a little disappointed (return trip on the Skyrail was great)
and were looking for a real tropical experience. The Reef Magic tour
was simply fantastic and we enjoyed every minute.
We
left Cairns around 9am on the high speed Reef Magic catamaran
and headed out for the 90 minute trip to the Reef. The voyage
out was a little sloppy once we moved onto the open water but most
enjoyable. I had taken some Kwells as I suffer from sea-sickness and
they worked perfectly! We sat outside on the trip out and breathed the
cool salt air to ensure I didn't bring up breakfast, but on the return
trip we sat inside the comfortable saloon and I didn't feel crook at
all.
Although there were a quite a few people onboard the ratio of staff to
passengers was high and meant we were well looked after. We arrived at
the huge Marine World pontoon which is moored on the Outer Reef and
immediately hopped aboard the semi-submersible for a tour of the Reef.
Viewing the extraordinary array of coral and fish through the glass
sides was a thrilling way to begin our stay on the Reef.
The tour package includes snorkel, goggles and fins and all the
swimming you can ask for. An extra option we elected to take was a
guided snorkel tour with a marine biologist. This is a wonderful way to
have the intricacies of the Reef explained as you swim about. During
this excursion we came upon the huge Wrasse nicknamed 'Wally' which you
can see below. This huge fish swam right up and then moved off to
follow the photographer as she took underwater snaps around the Reef.
The marine biologist then handed me a sea cucumber and spoke
about the different varieties found along the Reef before
carefully placing it back on the sea floor.
After
our snorkelling exercise came a call for lunch, a hot and cold buffet
and the quality of food was excellent. The helicopter buzzed overhead
during lunch as people took in a birds eye view of the Reef. We
ventured back onboard the Reef Magic and finished lunch with a drink
from the bar. This is one tour certainly worth taking and includes:
- 5 hours at the Outer Barrier Reef Marine
- World Activity Platform offering shelter and shade, with showers and
change rooms
- Underwater Observatory and fish feeding
- Marine Biology presentation
- Personalised and friendly service
- Unlimited snorkelling
- Dedicated Dive tender for certified divers
- Semi Submersible tours
- Morning and afternoon tea
- Hot and cold buffet lunch
The
Great Barrier Reef
The Great Barrier Reef is the world's largest coral reef system,
composed of over 2,900 individual reefs and 900 islands stretching for
2,600 kilometres (1,600 miles) over an area of approximately 344,400
square kilometres (133,000 sq miles). The reef is located in the Coral
Sea, off the coast of Queensland in northeast Australia.
The Great Barrier Reef can be seen from outer space and is the world's
biggest single structure made by living organisms. This reef structure
is composed of and built by billions of tiny organisms, known as coral
polyps. The Great Barrier Reef supports a wide diversity of life, and
was selected as a World Heritage Site in 1981.
A
large part of the reef is protected by the Great Barrier Reef Marine
Park, which helps to limit the impact of human use, such as overfishing
and tourism. Other environmental pressures to the reef and its
ecosystem include water quality from runoff, climate change accompanied
by mass coral bleaching, and cyclic outbreaks of the crown-of-thorns
starfish.
The Great Barrier Reef supports a diversity of life, including many
vulnerable or endangered species, some of which may be endemic to the
reef system.
Thirty species of whales, dolphins, and porpoises have been recorded in
the Great Barrier Reef, including the dwarf minke whale, Indo-Pacific
humpback dolphin, and the humpback whale. Large populations of dugongs
live there.
Six species of sea turtles come to the reef to breed – the
green sea turtle, leatherback sea turtle, hawksbill turtle, loggerhead
sea turtle, flatback turtle, and the olive ridley. Around 125 species
of shark, stingray, skates or chimera live on the reef. Close to 5,000
species of mollusc have been recorded on the reef, including the giant
clam and various nudibranchs and cone snails.
215
species of birds (including 22 species of seabirds and 32 species of
shorebirds) are attracted to the reef or nest or roost on the islands,
including the white-bellied sea eagle and roseate tern.
Seventeen species of sea snake live on the Great Barrier
Reef. They take three or four years to reach sexual maturity and are
long-lived but with low fertility. More than 1,500 species of
fish live on the reef, including the clownfish, red bass, red-throat
emperor, and several species of snapper and coral trout. Forty-nine
species are known to mass spawn, with eighty-four other species found
on the reef spawning elsewhere in their range.
Four hundred species of corals, both hard corals and soft corals are
found on the reef. The majority of these spawn gametes, breeding in
mass spawning events that are controlled by the rising sea temperatures
of spring and summer, the lunar cycle, and the diurnal cycle. Reefs in
the inner Great Barrier Reef spawn during the week after the full moon
in October, but the outer reefs spawn in November and December. The
common soft corals on the Great Barrier Reef belong to 36
genera. Five hundred species of marine algae or seaweed live
on the reef, including thirteen species of the genus Halimeda, which
deposit calcareous mounds up to 100 metres (110 yd) wide, creating
mini-ecosystems on their surface which have been compared to rainforest
cover.
We would love to spend a bit more time out on the water and not be so
rushed, so next time it might be on a chartered sail boat.
