The fire brigade works overnight to contain a large wildfire south of Sydney, and the flames go out of control on Saturday afternoon.
The fire is burning in Royal National Park, south of Heath Court and east of Princes Highway.
It is understood that the fire started around 1 pm after the open burning containment line was broken by a spotfire.
Spotfire quickly went out of control and turned into a 200-hectare flame. On Saturday afternoon, firefighters called in a water bomber to contain the flames.
The situation was alleviated and the crew managed to bring the fire back under control.
The fire caused a large delay on the Princes Highway and traffic was backed up for hours in both directions.
Some of the highways and surrounding roads were closed intermittently throughout the afternoon, prompting drivers to delay their trip or use a different route.
Train services in the area have also been temporarily suspended and buses have replaced trains on the T4 Eastern Suburbs Line and the South Coast Line between Illawarra and Sutherland and Waterfall.
The flames are now burning northeast and the crew continues to work all night.
Currently, there is no threat to the property in the area and the Princes Highway is open in both directions.
