Organisation for the Rescue and Research of Cetaceans in Australia (ORRCA) president, Ronny Ling, said the 5000 kilometre trip to Queensland waters had begun.

"People complain about the ride to the hospital - these whales have to travel for months to have their babies. They travel to warmer water because baby whale blubber is very thin and it has to thicken before heading to the Antarctic," he said.

Mr Ling expected a spike in sightings from mid-June to early-July although a few whales per day have already been spotted at Tacking Point.

Pregnant whales will give birth and others may mate before heading back up the coast around November.

"Humpbacks are the main whales people will sight, however minke whales may pass and if we're lucky southern white whales. They are very special because at one point white whales were almost wiped out," Mr Ling said.

He predicted Port Macquarie residents may spot from 80-100 whales per day in peak season, with a total of 20,000 migrating through our waters.

"Port Macquarie whale watchers have a great advantage point, you have beautiful waters and some high points like Tacking Point. Normally whales travel two to four knots, sometimes eight knots, so they are slow moving, easy to spot and the whole family can watch."

Mr Ling also highlighted the Port Macquarie National Parks and Wildlife, in particular Andrew Marsh, for being a first class disentanglement team for whales along the North Coast.

Port Macquarie Cruise Adventures owner, John Fowler, said after completing 12,000 whale watching trips each year familiar creatures often appeared.

"We get to know the whales quite well and recognise them from their markings, rope burns, whale flukes and colouring. One whale in particular is Blade Runner. He was hit by a boat when he was younger and has some pretty noticeable scarring."

Port Jet owner, Jodi Heeney, hoped to spot world-renowned white whale Migaloo this season.

"Migaloo is an albino white whale who is tracked and spotted each year travelling the coast line. We missed him last year but would love to catch a glimpse of his beauty this time around," she said.

In 2014, Port Jet's previous owner Andrew Burt was able to take a photo of Migaloo and follow his journey through Port Macquarie.

"I recommend to anyone whale watching now, to also make a trip back when they've had their calves and head home. It's a magical experience to follow their journey," Ms Heeney said.
