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.

Journey down the East Australian Current all the way from the Great Barrier Reef to Antarctica. Discover how ocean currents create life on our planet and what you can do to protect our planet's blue heart.
