The 2011 Wollongong floods, beginning in March 2011, were a series of floods occurring throughout Wollongong and the Illawarra regions of New South Wales, Australia. The floods were the result of a storm cell covering most of the southern regions of the state and torrential rain in suburban Sydney and nearby regional areas. The Princes Highway was closed around Station Street, Albion Park and at Kiama after a tree fell and blocked the road. The Southern Freeway was closed at Berkeley and the Illawarra Highway was also closed.
