In November 2002 Julian Rocks became part of Cape Byron Marine Park with new
zoning plans being discussed over the next few years.
According to a story from the aboriginal 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
from Byron Bay..
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!
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!
