Ethical wildlife boat tours out of Eaglehawk Neck, sailing from the pier near the Blowhole about an hour south-east of Hobart. The two-hour-plus scenic cruise takes in sea cliffs, caves and the marine life of the Tasman coast, with commentary framed around ocean conservation and wildlife rescue, which the operator says is the reason it exists. Private small-group charters for up to twelve are also available, booked online by season.
