This whalewatch season in Hervey Bay, Australia marks an exciting continuation of Pacific Whale Foundation’s mission to protect our oceans and study the humpback whales in the East Australian population. These whales stop over in Platypus Bay every winter on their migration back to their feeding grounds in Antarctica. Pacific Whale Foundation (PWF) began its long relationship with Australia’s whalewatching capital in the 1980s when our Founder and Executive Director, Greg Kaufman, discovered the beauty of the humpback whales in Platypus Bay, off of Fraser Island, and pioneered the area’s first whalewatch on a borrowed fishing boat. Since then, Greg and the PWF researchers have been important figures in Hervey Bay, conducting photo-identification studies on these amazing animals each winter.
Breaching, or jumping out of the water, is a behavior that the PWF researchers in Hervey Bay and in Maui observe frequently. A commonly asked question is “Why do whales breach”? The short answer is that no one knows a single cause for this behavior; however, there are a number of theories about what drives such impressive whale acrobatics.
One possibility is that the whales breach just for fun, similar to humans and other terrestrial mammals when they are excited or playing. Another option is that they use breaching and other surface activity as a way of communicating to other whales. If you’ve ever been close to a breaching whale, you know that the sound is astonishing. The sound is also quite loud underwater and may be used to communicate the whale’s location or activity level to other whales in the distance. It has also been suggested that whales breach to deter predators or other perceived threats.
As part of the Hervey Bay Oceans Festival, our researchers had the opportunity to be involved in Paddle Out for the Whales–an event to help raise awareness of the threats whales face today.
The event involved paddling out on a craft of your choice (SUP, kayak, inflatable raft, or handmade) to observe a minute of silence acknowledging the importance of whales and the ocean to Hervey Bay. Before the paddle out began, a live Zumba session got the paddlers loose and limber. One of our research volunteers, Jaimi, paddled out by kayak to participate in the event while Research Assistant Jessica remained on land to give an informative talk about PWF’s research in Hervey Bay. A PWF booth was present at the event to sell items from our Australia-based gift shop, as well as engage with community members about the research in Australia. The event also featured live music, sandcastle building, and construction of a 6-foot papier mache whale.

Pacific Whale Foundation’s Australia research program is off to a great start this year. Based out of the town of Hervey Bay, we observe the whales as they migrate along the east coast of Australia, traveling south to their Antarctic feeding grounds. We have had some amazing whale encounters, and we are already starting to see mothers arriving with their calves. Our research staff and volunteers have been going out daily since mid-July to photograph the humpback whales that migrate through the region. The whales in this population mate and have their calves in the tropical areas of northeast Australia and Oceania. The bay is relatively shallow and protected by Fraser Island, offering a nice area for the whales to stop over during their long migration south.
Working from the MV Amaroo operated by the Hervey Bay Boat Club, our researchers take opportunistic identification photos of the underside of the whales’ tail flukes. Since each fluke is unique to the individual, these photos allow us to compare the fluke of each whale we see in the field with our catalog of known whales to determine the history of sightings for each animal. Additionally, the team tries to get photos of the dorsal fins and body of the animal which helps us assess overall body condition as well as any lesions or scars that may indicate injury or poor health.

Another terrific whale season is almost complete in Hervey Bay, Australia, as Pacific Whale Foundation’s research team come to the tail end of collecting fluke identification and distribution data that will be compiled with 30 years of research in the area.
Southern hemisphere humpback mothers and calves are the last to be spotted as they complete their annual southward migration to the Antarctic feeding grounds. PWF researchers are assimilating data to take back to our research headquarters on Maui, where photographs and findings will be analyzed.
Pacific Whale Foundation researchers arrived this week in Hervey Bay, a quaint community in northern Queensland. For the next few months, I will be documenting research efforts and managing our little shop as humpback whales make their annual migration from the subtropic waters of eastern Australia to their feeding grounds of Antarctica. Stephanie Stack, M.Sc. PWF’s Senior Research Biologist and Research Assistant Laura Behm will be photographing flukes and recording data of daily sightings for ongoing research in the area.
Began in 1984, Pacific Whale Foundation’s Australia humpback whale research program is the longest running study of this population. The overarching goal of PWF’s research is to advance understanding of humpback whale biology, population status and impacts of human activities on the population. PWF’s Southern Hemisphere Humpback Whale ID Catalog is a compilation of 31 seasons of research, combining detailed data on life history, behavior, spatial distribution, and human impacts.
