Millions of residents along Australia’s eastern coast are bracing for the arrival of a very slow-moving storm, the most southerly tropical cyclone to threaten the region in more than 50 years.

A category two storm heading for the east coast of Australia has forced airports to close and airlines to cancel flights in preparation for up to 80 mph winds.
