Assessing the Impacts of Marine Tourism on Humpback Whales

Swim With Whales Impact Study

Wildlife watching is a multi-billion dollar industry that spans the globe and can have potentially negative impacts on the targeted species. However, when conducted thoughtfully and respectfully, can have positive impacts not only on the animals but on their environments as a whole. Conservation education, regulation compliance, and continued monitoring and research contribute to the positive impacts of marine tourism.

In 2014, the Queensland government authorized commercial tourism companies to begin swimming with humpback whales, currently listed as a “vulnerable” species under the Australian Environment Protection and Biodiversity Conservation Act. We are investigating the  behavioral impact of commercial swim with whales tours in Hervey Bay. Our objectives are to better understand if humpback whales change their behavior due to in-water interactions with humans, identify factors which may influence behaviour change, and provide recommendations to governing authorities, resource managers, and tour operators to ensure that Hervey Bay’s  humpback whales are not negatively impacted by swim-with-whales tourism.
