A large number of firefighters remain on the ground working to slow the spread of the fire, which continues to burn in a southeasterly direction towards Barden Ridge.
Authorities urge residents of Voyager Point, Pleasure Point, Sandy Point, Alfords Point, Barden Ridge, Illawong, Menai and Bangor to continually check for updated advice from the NSW Rural Fire Service, as conditions can change quickly.
RFS spokesman Greg Allan said some properties had not escaped unscathed.
But on Sunday morning the NSW Rural Fire Service downgraded the bushfire to a "watch and act" alert.
By 5pm, some Menai residents were starting to relax.
Many property owners stayed to protect their homes from spot fires - luckily no homes or lives were lost.
Local MP Craig Kelly said because most of the communities in the area were quite bushy and remote, residents understood the risk of bushfires.
"So I'm sure everyone's been out checking their roof, making sure everything's wetted down and keep an eye on those spot fires".

Hundreds of people were evacuated from their homes on Saturday night, with the flames burning within metres of properties in Holsworthy and Wattle Grove.
An unspecified number of Menai and Barden Ridge residents left their homes after New South Wales authorities declared a state of emergency as nearly 100 firefighting trucks and 15 aircraft continued fighting back the blaze, Efe news agency reported.
The blaze was downgraded from emergency level to watch and act about 5.30pm on Sunday as conditions began to ease.
Wind speeds are expected to be similar today.
The temperature may remain a cause for concern, according to the RFS Deputy Commissioner Rob Rogers.
He said the aircraft had unfortunately already been returned to the United States because they were always sent back by the end of March when temperatures were traditionally cooler.
"As we say all the time, no one tolerates this in the community".
Reports say the unseasonably hot weather of the last few weeks is partly to blame, though police are also investigating what started the blaze and are appealing for witnesses.
