Embark on a whale-watching adventure from Sydney Harbour, where you'll cruise through the ocean waters to spot humpback and southern right whales as they migrate between Antarctica and the Great Barrier Reef. On board a custom-built catamaran with large viewing windows and spacious decks, you'll have excellent sightlines to take in the breathtaking views of the ocean and its inhabitants. During the tour, which lasts a couple of hours, you may also spot dolphins, seabirds, and other marine animals making an appearance in the ocean.
