Whales
can be seen from a number of vantage points at Point Lookout.
On the North Gorge Walk, excellent views are obtained
from Norm’s Seat and above Whale Rock. At
the Frenchman’s Bay end of Timbin Road, elevated
timber platforms have been provided, for views over
Boat Rock and The Group rocks just offshore.
Whales
can also be seen from the beach behind the breakers
midway down Main Beach.
On
their more leisurely return migration, whales can be
seen in the waters between Shag Rock and the more distant
Flat Rock. At these times Cylinder Headland and The
Stradbroke Beach Hotel are excellent vantage points.

Migration |
| |
In
the Southern Hemisphere humpback whales migrate from their
summer Antarctic feeding grounds, along Australia’s
continental coastline to tropical regions to breed and
calve in winter. Most humpbacks return to the same breeding
grounds for successive years. After
the migration passes Breaksea Spit at the northern end
of Fraser Island, it enters the sheltered waters of
the Great Barrier Reef and disperses widely between
the Outer Barrier Reef and the coast. Calving usually
occurs inside the reef at 18-19 degrees south, but has
also been witnessed off Point Lookout.

Observation |
| |
The
headland at Point Lookout is approximately 35m above sea
level, from which the line of sight horizon is 18km away.
Despite this, it is considered that the maximum distance
at which a whale could be seen was 10km under good weather
and sea conditions. |

Research |
| |
Since
1978, observers have been conducting systematic counts,
tracking and fluke identification off Point Lookout headland,
in an attempt to estimate the status of the whale stocks.
Commercial whalers exploited humpbacks to the fullest
between 1952 and 1962. They slaughtered about 10,000 along
the east coast alone, from localities around Norfolk Island,
Byron Bay and Tangalooma on Moreton Island. Populations
were reduced to very low numbers, to possibly fewer than
500 animals in total by the end of the 1962 season. |

Whale
Behaviour |
| |
|
| |
Breaching |
| |
Of
all the largest whales, humpbacks are considered to be
the most acrobatic and playful. It is a truly humbling
experience to see 30 tonnes of humpback leap clear of
the water, execute a perfect half twist with its splayed
pectoral fins and disappear in a mountain of ‘whitewash’.
This can occur many times in succession, however its purpose
remains unclear.
But the breach, as it is called, is only one of a number
of spectacular humpback behaviours seen in the waters
off Point Lookout.
|
| |
|
| |
The
Blow |
| |
A
powerful exhalation of breath is usually the first indication
that humpbacks are present in the area. Owing to an emulsion
of oil suspended in the blow, whale breath can be quite
fishy to smell. |
| |
|
| |
Fluke
Up Dive |
| |
Following
a blow, a humpback will often arch its back and roll forward
until only its tail flukes are sticking up out of the
water. Researchers have taken advantage of this particular
behaviour by compiling a photographic register of the
individual markings on each whale’s tail. The characteristic
arching of the whale’s back prior to a ‘fluke
up dive’ is also how the humpback got its unusual
name. |
| |
|
| |
Peck
Slapping, Tail Slapping |
| |
For
humpbacks, slapping their pectoral fins on the surface
of the water is something akin to an acrobatic feat. Each
pectoral fin weighs in the vicinity of several tonnes
and can be five metres long from base to tip. It is believed
the behaviour serves as a means of communication - a kind
of “I’m here” splash. The same holds
true for tail slapping, but it can also be used to indicate
aggression. |

|
| |
Spy
Hop |
| |
Humpbacks
are, by nature, highly curious animals and it can be quite
disconcerting to the first time whale watcher to see a
full size whale suddenly pop its head vertically out of
the water and take a good look around before sinking under-
water again. |
| |
|
| |
Fighting |
| |
When
male humpbacks come together in the breeding grounds and
compete for primary escort position with a female, fighting
occurs. Large males will battle it out through a combination
of head-butting, snorting, bubble blowing and inflated
lunging (lunging with their mouths full of water in a
bid to make themselves look larger). Males have also been
known to ‘motor boat’ on rare occasions -
a highly aggressive behaviour in which both males swim
at the surface and surge through the water side by side,
creating a huge bow wave. Dominant males may well have
to prove themselves several times during each breeding
season. |
