About this tour

Whale sightings guaranteed between mid-July and early October.

What to expect
You'll board a nimble 12-metre rigid inflatable designed for intimate group encounters. The three-hour journey cuts into Platypus Bay's protected waters, where humpbacks gather en route north or south. Marine scientists narrate behaviours in real time—breach patterns, tail slaps, social interactions—drawing on active research. The boat sits low enough for eye-level sightings and crisp photos. Expect genuine ocean science delivered by people who study these animals, not scripted tourism patter. The ride itself covers scenic ground past K'gari's coastline. Conditions dictate the experience: calm mornings yield clearer whale activity; rougher days test your sea legs but often produce dramatic sightings.
Good to know
Whales are guaranteed July 15–October 9 only. Dress for wind and spray regardless of season. No hotel transport provided; arrange your own to Hervey Bay's departure point. Children under six aren't permitted; those six and older need an adult supervisor. The boat operates rain or shine.
