NSW firefighters have taken advantage of easing weather conditions overnight to strengthen containment lines after a huge blaze broke out in the Royal National Park in Sydney’s south on Saturday.
The fire, which destroyed more than 1800 hectares of land, forced hikers and tourists to evacuate the area.
NSW Police say the fire is being treated as suspicious and investigations are under way.
The national park will remain closed today as conditions are forecast to worsen.
A number of other fires continue to burn across the state, although there were no emergency warnings at the time of writing.
Total fire bans have been declared for the Southern Ranges, Central Ranges, Greater Hunter and Greater Sydney.
The mercury is expected to top 43 degrees in both Penrith and Richmond today.
