As we reach the end of the East Australian Current, its remaining flow mixes into the Antarctic Circumpolar Current and the Indian Ocean. Our whales finally leave Tasmania's temperate waters on their journey to Antarctica.

Ride the East Australian Current through the subtropical marine environments of New South Wales with a pod of migrating humpback whales, we explore how the warm flow sustains and transforms whole ecosystems.

We begin our ocean odyssey on the Great Barrier Reef, where the East Australian Current first meets the coast and begins its journey south, following a clownfish hatchling on his maiden voyage on the East Australian Current.
