Residents stranded in the NSW South Coast town of Batemans Bay have been warned to seek shelter as fires surrounding them jump containment lines.
Warning levels are now at emergency level with many locals already forced to flee their homes and set up at evacuation centres.
Residents around Clyde Mountain, including North Batemans Bay, Surfside, Long Beach, South Durras, Maloneys Beach have been warned it is too late to leave and must seek shelter as the firestorm draws near.
The fire jumped the Kings Highway a short time ago and with hundreds of properties at risk, some residents have chosen to stay with their homes and try to protect them.
Over 30,600 homes and businesses are also without power in the Batemans Bay and Moruya region due to the fires affecting infrastructure in the area according to Essential Energy.
They warn that further outages are likely as the fires continue to grow.
As residents of Batemans Bay desperately wait out the firestorm, close to 150 other blazes continue to burn across NSW with 12 now at "emergency" warning level.
Sweltering temperatures and strong winds are fanning flames as emergency crews struggle.
NSW Rural Fire Service community safety officer Marty Webster says there is an "enormous" amount of fire in southern NSW and conditions have been worsening in line with forecasts.
"Our grave concern is for people who haven't acted on our advice and are in bushland areas," told media this afternoon.
As well as the NSW South Coast, emergency warnings are in place for fires in the Snowy Monaro and Snowy Valley regions as well as the 268,000-hectare Green Wattle Creek blaze southwest of Sydney.
More than 3000 firefighters are on the frontline with 31 specialist strike teams in place across NSW.
Northwesterly winds have been whipping fire grounds in southern NSW and pushing bushfires towards the coast.
