This year's Human Whale occurs on Sunday, July 14 and event organiser Mel Turner, from Moonshadow-TQC Cruises, is hoping enough people turn up so that the human whale can deliver a calf.

"There's a slight possibility the whale may have a calf this year, but in order for that to happen we need a lot of people to turn up," she said.

"The whale is traditionally about 100m long, and you can flesh that out with 1300 or so people. Another 500 means we could do a calf.

"So if you want to see a calf, be part of history in the making and be there."

Last year a total of 1318 people helped form the outline of a humpback whale on Fingal Beach, eclipsing the 2017 record by more than 300 and this year organisers are hoping to break the 2000 mark.

As well as celebrating the whale migration season the event drives home conservation messages about maintaining, protecting and preserving the area's abundant natural features.

"We'll have interactive store holders there with messages about how preserve, maintain and protect our marine environment and by reducing the rubbish that ends up in the waterways," Mel said.

The Human Whale [event] makes a fun day out for the family and is timed to coincide with the winter school holidays and the thriving whale watching season along the Humpback Highway.

About 35,000 whales are expected to travel this highway during winter as part of the southern migration.

"The location is perfect with space for families to move around the various stalls, play in the grounds' park, amenities and utilise the restaurant and cafe's nearby, it [event] has been well received by those attending," Mel said.

Fingal Bay Surf Life Saving Club will have its barbecue firing on the day and Northpoint Survey will map out the 100 metre whale outline on the beach, used to help guide participants into place.

"Support from this year's sponsors has been extraordinary," Mel said. "Without their support we would struggle to hold the event. All of the Fingal businesses who have sponsored have really taken ownership of the day.

"It's a sensational location and I am confident the village of Fingal will continue to grow this unique, fun and family friendly day out.

"And of course, without Northpoint Survey, we wouldn't have a whale."

Registrations to participate will open at 10am in the park outside the surf life saving clubhouse.

Participants will be guided into formation at 11.45am.

A drone will capture the completed formation at noon.
