Everything you need to know about humpback whales on the Sunshine Coast.
From migration patterns to unforgettable swim encounters
With the arrival of winter, one of nature’s most extraordinary journeys begins. Just off the shores of the Sunshine Coast, thousands of humpback whales make their way along the coast. The extraordinary creatures migrate along the East Coast of Australia — and here, in these calm, blue waters, we’re lucky enough to witness it all up close.
Curious about the migration, eager to spot a breach from the bow of a boat, or dreaming of swimming alongside a whale? This guide will give you everything you need to know about humpback whales on the Sunshine Coast.
Here’s why the Sunshine Coast is so special
The Sunshine Coast is one of the best places in the world to observe and swim with humpback whales. Sheltered by the outer reefs and islands, our conditions are often calm and clear, with winter water temperatures ranging from 19 to 23°C and visibility often reaching 15 to 30 metres — ideal for in-water experiences.
We’re located just minutes from the continental shelf. This means we reach whale territory quickly, giving guests more time in the water and less time commuting. For this reason we’ve chosen Mooloolaba as our home base — it offers both accessibility and stunning ocean conditions. With these ideal conditions in place, it’s no wonder the Sunshine Coast is a prime location for the humpback whale migration.
The Humpback Whale Migration: When and Why
Understanding the migration timeline ensure you have the best chance of encountering these magnificent creatures in their natural habitat. Australia’s East Coast Humpback Whale Migration sees over 35,000 whales travel from the freezing waters of Antarctica. They make their way to the warm, tropical breeding grounds of Queensland’s northern coastline.
• June to early July: Most whales are heading north — these early-season whales are often adult males and pregnant females.
• Mid-July to late August: We begin seeing both northbound and southbound whales in the area, a crossover period that can bring increased activity and unpredictable encounters.
• September to mid-October: This is the sweet spot for swimming. Mothers and calves rest in the shallow waters, and conditions are usually calm and sunny.
• Late October to early November: Most whales are heading south again, often with playful calves in tow.
These intelligent, social mammals migrate to breed, give birth. As a result, they allow their calves to grow and gain strength before returning to Antarctica.
Whale Behaviours to Watch For
Every encounter is different, but some of the most exciting moments come from the whales themselves. Humpbacks are known for their acrobatic displays and curiosity, which means we often observe:
• Breaching – launching their entire body out of the water
• Tail slapping – used for communication or play
• Spy hopping – when a whale pokes its head vertically out of the water to look around
• Logging – whales resting near the surface, calm and still
• Mum and calf bonding moments – tender, quiet, and unforgettable
• Blow Spouts – the exhalation of air and mist from the whale’s blowhole, signaling their presence just below the surface
• Socializing with other whales – playful and social behavior, often seen in groups as they communicate and interact with each other
Occasionally, a whale might even approach us. This could mean swimming beside or underneath the group. These moments are powerful — and always on the whales’ terms. While watching humpbacks from a distance is already special, getting in the water with them offers a deeper, more personal connection.
Swimming With Whales — A Deeper Experience
At The Pressure Project, our small-group whale swims offer more than just a chance to tick something off a bucket list. In addition, they provide a deeper connection with the ocean and these majestic creatures.
We limit group sizes to just a few guests per guide for safety, calmness, and respect. Our team are trained freedivers who guide guests through gentle snorkelling techniques and proper approach behaviour. We also teach body language awareness to give you the best possible chance at a meaningful encounter, while keeping the whales’ comfort front of mind.
In 2024, we saw whales on 100% of our trips, with successful swims, and 93% resulted in successful swims. However, it’s not about the number. It’s about presence.
Our Ethical Approach
The Pressure Project takes the role as ocean stewards seriously. All encounters are conducted under the Australian National Guidelines for Whale and Dolphin Watching and our own internal protocols, built from experience, training, and deep respect for marine life.
On our tours we do not chase whales or force interactions. Every swim is on the whales’ terms — always. When whales approach us, we turn off the engine, remain still, and allow them to inspect us on their own pace.
We’re also in regular communication with local researchers and marine experts, contributing to citizen science and helping to protect the future of these majestic creatures.
Join Us This Whale Season
Watch from the boat or take the plunge — the choice is yours. Regardless of how you experience it, our whale encounters on the Sunshine Coast are personal, powerful, and unforgettable. With the smallest groups in the region, our tours are designed to give you space, calm, and the best possible chance to connect with the ocean in a way that stays with you forever. The Sunshine Coast is definitely one of the best places to swim with whales in Australia. Even in the world!
