A monster waterspout was filmed thundering across Batemans Bay on the NSW south coast yesterday afternoon.
Witnesses reported seeing a fat column of rotating cloud, mushrooming into a darkened sky, off Long Beach at around 2pm AEDT.
The spectacle lasted about 15 minutes as the waterspout moved from the middle of Long Beach around the headland before breaking up.
Some managed to record it on their mobile phones.
"I've definitely not seen anything like it before," one resident, who watched the waterspout from her balcony while having lunch with friends, told the Daily Telegraph.
The waterspout offered a dazzling exclamation point to a storm cell that brought heavy rainfall and wind gusts of up to 100km/h to the state's north over the weekend.
The NSW State Emergency Service was kept busy, with 150 callouts on Saturday and Sunday, most from the northern NSW township of Woodburn.
A senior meteorologist at the Bureau of Meteorology told the Sydney Morning Herald specific conditions were required for waterspouts to form – unstable air, warm water and a wind shear.
''They are impossible to forecast,'' he said.
''They can be dangerous if in the vicinity, on a surfboard or swimming, but you would have to be very unlucky.''
