Current Vortex off Australian Coast – February 21st, 2009
The East Australian Current flows from North to South along the eastern coast of Australia. It is the result of the collision of the South Equatorial Current colliding with the Australian mainland.
In shallower waters along the Australian continental shelf the East Australian Current may be as fast as 7 knots, but its speed in most places is usually around 2 or 3 knots.
The East Australian Current causes a current vortex in the Tasman Sea between Australia and New Zealand, visible here near the center.
It has also been noted that this current transports tropical marine fauna to habitats in sub-tropical regions along the south east Australian coast.
