Without home phones and mobile reception, Brooman and Mogood residents relied on internet messaging to keep each other safe as a front escalated the Currowan fire on Tuesday.
Amelia Robson, who lives on the Sheep Track between Brooman and Termeil, said her neighbours have a chat group on Facebook for emergencies, so they're all aware of what could impact their lives and properties.
"As long as the internet stays connected we're OK," she said.
Clyde River Berry Farm owners Sharyn Prendergast and Allan Dixon were alerted by a neighbour, who was told of the bush fire threat by a friend in town.
It was hot and windy throughout the day, but they couldn't smell smoke or see a fire when they were told of the threat.
They remained connected with their neighbours throughout the evening with social media and also kept on top of the threat with their Fires Near Me app.
RFS crews eventually visited their property in the evening an updated them on the status of the blaze.
Mrs Robson, who had evacuated her children and animals to friends in Bawley Point, said it was "pretty scary" on Tuesday.
"The wind was so scary blowing ash. We lost count of how many trucks continued to go past. It felt like the eerie calm before the storm overnight, it was just so quiet and still."
The smokey smell has eased in Ulladulla as have conditions, reportedly on the fireground. However, the fire is burning in a north easterly direction towards the area of Brooman.
Mrs Robson said they are waiting to see what the wind does today.
"Mother Nature will hopefully look after us and keep it in the forest away from friends and family further in Brooman," she said.
"The firies know their stuff and we're just waiting to be advised."
