Australia's Newcastle Airport cancelled flights Sunday after its roof collapsed following a sudden deluge of rainfall. 
At around 1pm, shortly before the Bureau of Meteorology issued a heavy rainfall warning for the Newcastle area, gutters in part of the Williamtown airport terminal flooded with water, causing a section of the roof to cave in. 
Most flights, including from domestic carriers Jetstar, Virgin and Regional Express were cancelled. However, regional carrier Pelican Airlines remained operational, with a flight set to arrive later on Sunday afternoon. 
Reports did not mention injuries to passenger or airport staff.
