Julian Rocks
Contributed by Wandy Hochgrebe
According to a story from the Bundjalung people a jealous husband
threw his spear at the canoe of his wife and her lover. The canoe broke
in two and sank to the bottom of the ocean. Only the back and the front
of the boat stuck out of the water, creating a rock formation just 2.5
km off shore.
Named by Captain Cook in 1776, Julian Rocks in
Byron Bay consists of ancient sedimentary rock, remains of a volcanic
eruption more than 20 million years ago. It is an extension of Cape
Byron separated by water and forms a most unique marine reserve,
providing shelter and food for more than 500 tropical and temperate fish
species alone!
Since 1982, after 10 years of lobbying by local
users, Julian Rocks falls under the Fisheries and Oyster Farms
Regulation. This means that injuring, disturbing and removal of all
forms of marine fauna within a 500 meter radius of the rock is
prohibited. Starting on November 2002 Julian Rocks has become part of
Cape Byron Marine Park with new zoning plans being discussed over the
next few years.
Not only does Julian Rocks provide resting and
nesting grounds for many seabirds, such as seagulls and cormorants,
underneath the water is an invisible world with abundant marine life
present.
With water temperatures and
currents changing throughout the year there are many seasonal visitors.
The grey nurse sharks come to Julian Rocks during the winter months,
presumably to breed. Although these sharks look ferocious with their
mouths slightly opened and their teeth sticking out, it is perfectly
safe to dive with them. In spring the blue tang pays Julian Rocks a
visit. This is a fish, which can be easily distinguished by its blue
body and bright yellow tail. Schools of big-eye trevally are most common
in summer. The docile leopard sharks can be seen on almost every dive
during mid-summer when the waters are warmest. The spotted patterns on
their skin gives them their name. Most of the time they lie resting on
the sand, but if you are lucky you can see them swimming, moving their
long tail slowly. In summer and early autumn manta rays cruise elegantly
through the waters surrounding the rock. Sometimes feeding and
definitely curious they are fantastic to encounter.
And then there are of course the
‘regulars’ like different species of wobbegong sharks,
turtles, cuttlefish (family of the octopus), schools of white spotted
eagle rays, egg-cowry shells, moray eels, banner fish, giant guitar fish
and shovel-nose rays. Sometimes there are so many fish around, you can
hardly see where you are going. Not to mention all sessile animals
(attached to substrate) like tunicates, colourful sponges, both hard and
soft corals, giving you the feeling you are floating through some
beautifully landscaped underwater garden.
The Rock also forms a
home for rare species such as the leaf scorpion fish, the pineapple fish
with bioluminescent organs under its eyes, the shy blue devil fish,
white banded anemone fish and a species of nudibranch previously thought
not present in Australian waters (Noumea labouti). (A nudibranch is a
colourful underwater snail without a shell, carrying its respiratory
organ on its back)
The interaction of tropical and temperate
species makes every dive an exhilarating adventure. The three minute
boat trip to the rock is almost as exciting: surfing the waves sometimes
accompanied by playful dolphins. From May till September the Humpback
whales come past Byron Bay and can easily be spotted from the boat. With
water temperatures up to 25 degrees Celsius and visibility of 20 meters
at most times there is really nothing to complain about.
Fortunately the dive operators in Byron Bay also realise the value of
this Aquatic Reserve. Moorings have been put in place and are taken care
of, so destructive anchors are not needed. And since there are only a
limited number of commercial vessel launching licences available, no
over-diving can take place.
All different dive sites around
Julian Rocks are equally impressive and offer dives that are spectacular
for the novice and the very experienced underwater explorer!
