Migrating Mammals In Australia

As we all know whales migrate along the east coast of Australia between the months of May to November. But they are not the only mammals that migrate. It is not uncommon to see Bottlenose Dolphins, Dolphins, Common Dolphins, seals and Orcas traveling with the whales. The variety of whales you can see will include Southern Right Whales, Bryde's Whale, Minke Whales, Pilot Whales, Humpback Whales and False Killer Whales.


Northern Whale Journey
May - August

In May there are literally hundreds of Humpback whales heading north from the cold waters of Antarctica. The peak time is in June as large numbers of whales pass by Sydney. The end of August early September sees the last of the Humpback whales heading north to the warmer breeding grounds.

During the northern Migration it is not uncommon to see the males trying to impress the females by breaching the surface of the water.

Southern Whale Journey
August - September

This is probably the most fascinating time of the year in the migration of whales going past Sydney. The majority of the whales are on their way north and now we see the beginning of the first whales going south again. This cross-over point allows for differnet interactions between the whales.
It is common to see the Humpback whales circling our boats and coming right up to us. They call this mugging and it it truly a lifetime experience to get close to these enormous beautiful mammals.

Mothers and Calves
October - November

Another fascinating period in the whale migration along the east coast of Australia. This is when the calves and their mothers go by Sydney. Their pace is a lot slower as the calf is just maturing and doesn't have the speed of the larger whales as they head south. On the journey, the mother will be teaching the calf to breach the water among other things.

There is a lot of playful activity going on between mother and calf and if you are lucky you will see both of them breaching the water's surface.
