Flooding in parts of New South Wales was declared a natural disaster on Sunday and residents in flood-hit areas west of Sydney were evacuated overnight as Australia’s most populous state continued to be hammered by rain.
Sixteen areas of New South Wales, primarily in the north of the state, were declared "disaster ridden,” NSW Police and Emergency Services Minister David Elliott said in a press conference on Sunday.
"Regrettably, parts of the mid-north coast are experiencing a one in 100 years event,” NSW Premier Gladys Berejiklian told journalists.
Parts of Port Macquarie, some 400 kilometres north of Sydney, and several nearby towns flooded, while further south Taree was in the grip of a flood rivalling its worst on record 92 years ago.
In nearby Mondrook, a three-bedroom cottage was swept away from its foundation by floodwater in footage shown on local television over the weekend.
The premier said that, however, the area of major concern was the Nepean Valley - incorporating major urban centre Penrith, part of Greater Western Sydney - where local authorities were "envisaging a one in 50 years event.”
The NSW Bureau of Meteorology (BoM) said in a Sunday warning that the Nepean Valley was set to experience its worst flooding in 50 years as the Warragamba Dam - Sydney’s main water source - began spilling on Saturday afternoon causing river levels to rise along the Nepean and Hawkesbury rivers.
Berejiklian warned that, after a number of residents in flood-hit areas were already evacuated on Saturday night, a further 4,000 people in the "Hawkesbury region and parts of western Sydney” may be next.
On Saturday night the NSW State Emergency Service (SES) ordered anyone in low lying areas of Agnes Banks, Pitt Town Bottoms, Pitt Town North, Cornwallis, Gronos Point and North Richmond, some 50 kilometres west of Sydney on the Hawkesbury river, to evacuate.
The BoM on Sunday morning warned of further heavy rainfall and damaging winds, with a severe weather warning covering almost 900 kilometres of coast from Wollongong, south of Sydney, to Lismore near the border with Queensland.
A severe weather warning was also in place just west of Canberra.
"We are expecting to see river levels that had started to just recede slightly ... peak again probably later today and potentially even again tomorrow as the rainfall comes back for a third hit,” SES Deputy Commissioner Daniel Austin told Channel 9’s Today Show on Sunday morning.
Austin added that SES was planning their operations "well past Easter,” which falls on April 4.
"Unfortunately, of course, just because the rain stops it doesn’t mean that the rivers go back [to normal levels] straight away.”
Meanwhile NSW police said two hikers who on Saturday remained "stuck between two large bodies of water” in the Blue Mountains, west of Sydney, were among the over 670 people rescued since the severe weather event started on Friday.
Police were also looking for a bodyboarder believed to be "missing in waters” at Coffs Harbour, some 430 kilometres north of Sydney.
More than 6,700 calls were made to the SES since the weather event started, NSW SES Commissioner Carlene York told journalists. So far there are no reports of deaths.
The heavy rain was expected to keep falling on NSW until Thursday, according to the latest forecast.
