BRISBANE, Australia (AP) — Early wind and rain from a rare tropical cyclone began lashing part of eastern Australia on Thursday as schools were closed, public transport was stopped and desperate residents got around shortages of sandbags by buying potting mix.

Australia braced for a rare east coast tropical cyclone that is swirling towards Brisbane, its third-most populous city, with authorities urging residents in flood-prone suburbs to evacuate soon.

Millions of residents along Australia’s eastern coast are preparing for the impact of the most southerly cyclone to threaten the region in more than five decades.
