Everything You Should Know About Whale Migration in Eastern Australia

As observed by several marine biologists and lovers of the ocean, a whale is not as violent a creature as sharks are. Although whales are enormous in size, they are also among the most gorgeous sea creatures and have been around for hundreds of years. Throughout the years, whales have been hunt down to eat, store as prizes and keepsakes, and as a major consequence, they are fast going extinct when they shouldn’t have been. For this reason, most countries have introduced specific laws to protect the stunning mammals of the oceans.

The behaviours of all kinds of whales and dolphins has been observed in great detail by marine biologists and whale watchers that attend notable tours such as Oz Whale Watching. One of the question regarding whales, which comes to the mind of many people is: what exactly triggers a whale migration off the coast of Eastern Australia?

What Triggers a Whale Migration?

Whale migration off the coast of East Australia is a result of the freezing water during the months of the Antarctic winter. During this period of the year, southern whales head north, passing by the Eastern coastline of Australia. The need to migrate stems from three specific reasons:

Protect the Young

Naturally, the cold conditions of the freezing water can result in the death of baby calves. Whales are generally warm-blooded animals, and give birth during the second half of the year when the climate is a lot warmer. If the whales did not migrate, the water can become fatal for their calves and cause them to die.

The Need to Eat

Most whales exist on feeding off other fish, such as Krill, to survive, although many of them might also hunt down other sea creatures such as sea lions. However, because of the cold temperature of the water, other fishes and sea creatures choose to migrate as well. Due to this reason, whales must migrate otherwise they are likely to starve to death because of scarcity of food. This is done not only to save them but to protect their offspring as well.

Breeding Season

The months of May through to September are the breeding months for whales. The northern waters are a lot warmer in these months which make them the ideal grounds for the whales to breed in. Therefore, migrating from the cold waters of the southern part to the warmer waters is necessary for whales to breed their species and save themselves from freezing or starving.

Which Whales Migrate?

Within Australia, most of the whales that are observed migrating from the southern waters are humpback whales. During the month of May, the water in the coast of East Australia are a lot more warm and comfortable for the whales which is why, they choose to hurry off to those waters as early as May or even March, depending on the climate and temperature of the ocean.
