This section is home to some very good coral reefs for scuba diving
and snorkelling. Diving is easy and perfect for beginners.
These reefs are home to abundant fish life and healthy coral.
Due to a vigorous code of practice by all operators, those heavily
visited reefs are in very good condition. This is very good tropical
diving, especially if you have not dived tropical reefs before.
However, if you want to see the best of tropical diving in Australia,
you need to travel a little further to areas like the Ribbon Reefs
or in the Coral Sea. Experienced tropical divers will appreciate
the pristine dive sites that are the reward of the extra time and
distances travelled.
Location
The reefs are located around 50 - 65 km (30 to 40 miles) off the
coast from Cairns or Port Douglas (90-120 minutes by boat). Out
of Cairns you can visit reefs like Norman, Saxon, Hastings, Flynn
and Milln Reef. The most popular reefs out of Port Douglas are Tongue
and Opal and Agincourt Reef.
In only 45 minutes you can drive from Cairns to Port Douglas by
car or bus. The coastal road is a scenic treat that you should not
miss! Transfers between the towns can easily be organised.
Logistics For Dive Excursions
It is easy to get to these inner reef sites. You have the choice
of day trips to the reef and over-night live aboard trips. The dive
school live aboards visit the reefs out of Cairns. With them you
can take 1 to 5 night excursions. They have mostly open water students
and snorkellers on board, but they do cater for certified divers
as well.
If you prefer to take a day trip, take one of the fast vessels
that travel at 20-24 knots to the reef and you will arrive at the
reef within 90 minutes. Day boats out of Port Douglas allow up to
3 dives per day. You receive a concise dive briefing and a dive
master to guide you on the dives. With day trips out of Cairns,
up to 3 dives per day are offered. A good dive site and safety briefing
is given and a buddy allocated, if you do not already have one.
What To See
Features of these reefs are pinnacles, lagoons, drop-offs, caves
& gutters and very pretty coral gardens. The reefs display a huge
variety of tropical marine life with big schools of colourful reef
fish such as parrotfish, sweetlips and others. You may see also
blue spotted stingrays in the sand, eels, octopus, molluscs, flatworms
and sea stars.
Pelagics are rather rare. You might come across small whitetip
sharks and with a bit of luck barracudas or grey reef sharks. The
typical features for the GBR are the beautiful giant clams. There
are many clams, all adorned with different colours.
Types Of Diving
Diving here is pretty easy, ideal for novice divers. Hardly any
currents, and the best diving is to be found in the shallows, where
most of the activitiy is happening. Maximum depth is between 15
and 30 meters (45-100 feet), average depth about 18 metres. The
reef tops come up to about 2 to 4 meters below the surface - ideal
for snorkellers as well. Average visibility is about 10 to 20 meters
(30-60 feet), on a very good day even 30 meters (100 feet).
Dive Sites Out Of Cairns
- Milln Reef: "Whale Bommie" is located 100 metres out
from the main reef and starts in 25m of water. Small caves and
large gorgonian fans along with hard and soft corals and many,
many tropical fish can be found here. "The Swimming Pool" is a
shallow dive, 10-12 m offering a large selection of fish and corals.
This is a very nice site for night dives too.
- Flynn Reef: "The Coral Gardens" is a unique dive site
and as its name implies, divers are rewarded with a "garden" of
coral incorporating a wall dive, dropping off to 27 metres. Along
the wall you might see barracuda, mackerel, stingrays, turtles
and sharks. One of the best dives in that price range out of Cairns!
- Gordon's Reef: This reef has excellent corals and some
turtles. It has its share of swim throughs. It is almost like
being in a maze. There is one spot with beautiful anemones with
clown fish, called "Clownfish city".
- Saxon Reef: Saxon Reef is quite large with over 20 moorings,
meaning 20 different dive sites. For example, you can do a wall
dive or shallow dive, with the wall ending in 8 metres of water.
In the sandy area, you come across a number of small coral heads,
which have all sorts of interesting creatures living on them -
nudibranchs, the odd lionfish and damselfish.
- Norman Reef: Fantastic Swim throughs and gullies. Beautiful
hard coral gardens with many giant clams in all sizes and colours.
During your dive you might come across a huge maori wrasse or
a few friendly batfish.
- Michaelmas Reef: A beautiful sandy cay (Michaelmas Cay)
with the reef close to it. There are a couple of dive sites at
Michaelmas Reef. You dive amongst coral bommies where you find
sea stars, batfish, lionfish, turtles and more.
Dive Sites Out Of Port Douglas
Reefs such as Agincourt Reef, Tongue Reef, Opal Reef are visited
by the day vessels. The dive sites are comparable with the sites
in the Cairns area however, the visibility is often a bit better
in the Port Douglas area.
- Agincourt Reef: There are about 16 diferent dive spots
at Agincourt Reef, and they are superb. This is the best diving
you can get during a day trip. "Nursey Bommie" is a large coral
head in 24 metres, with pretty, spiky soft coral. While cruising
aroud the bommie you might meet the huge 2 resident moray eels
that live here. There is no shortage of giant clams and anemones
with their clown fish.
- Tongue Reef: There are some large plate corals at Tongue
Reef. Sweetlips like to hide underneath them. A 35 kg (87 lbs)
maori wrasse might be waiting for you under the boat and follow
you during the dive. He is hoping to get something to eat, as
the dive masters feed him from time to time. The giant clams here
are quite large and extraordinarly pretty.
Seasonal Events
November - Coral Spawning: Coral Spawning is often called
"Sex on the reef". That's what it is! Each year, corals release
their eggs and sperm at the same time which makes for a visual feast
for the voracious scuba diver ! It usually happens 4 nights after
the first full moon in November. It is an impressive event and night
dives are spectacular. A lot of critters are active, as this is
a feast for all reef dwelling creatures!
