Embark on a once-in-a-lifetime adventure and make the most of this Hervey Bay cruise. As you ride a smaller-than-standard boat, you'll enjoy water-level views of the bay's humpbacks while keeping a respectful distance. With luck, you'll see mothers and calves, and you'll hear whale songs via a hydrophone. An onboard naturalist will provide commentary for extra insight, and you'll have a choice of departures to give you flexibility.
