A handful or residents in Sydney's northwest are still awaiting the all clear to return home more than a week after being ordered to evacuate amid major flooding.
Large tracts of NSW went underwater over the past two weeks as rivers filled by torrential rain broke their banks.
Tens of thousands of people were evacuated from homes across the state, with Sydney's Hawkesbury-Nepean Valley and the mid north coast the hardest hit.
As the clean up from the widespread flood continues in earnest, evacuation orders remain in place for four areas along the Hawkesbury River.
Residents living in parts of Pitt Town Bottoms, Cornwallis, Freemans Reach and Pitt Town North are still waiting for the State Emergency Service to allow them to return after evacuating on March 21.
A sewage spill has also kept some people from returning home in Stuarts Point, near Nambucca Heads on the NSW mid north coast.
An evacuation order was issued on March 26, after septic systems overflowed into yards and streets, impacting 45 homes, police say.
NSW Health deemed there to be a health risk from faecal matter and bacteria in the discharge.
Impacted streets have now dried out and been disinfected, and all roads are open again.
Individual homes are still part of the exclusion zone however, with authorities assessing them before people are allowed to return.
