A number of whales have been spotted in Lower Eyre Peninsula waters recently, signalling the start of sightings in the region.
A humpback whale and its calf were spotted on Monday morning off of North Shields, before they were sighted in Boston Bay near the Port Lincoln Wharf.
On Tuesday a southern right whale was spotted quite a distance from the shore in Sleaford Bay.
Department for Environment and Water spokesperson Chris Thomas said the annual migration of whales occurred during the cooler months, which was when they mated, gave birth and nursed their young.
"Whale-watching is a fantastic nature-based experience, about 400,000 people take part in this activity each year in SA," he said.
The whale migration begins each year in May and runs through until November.
