Two homes and two sheds have been lost in the NSW Bega Valley as a bushfire west of Merimbula burns out of control.
The RFS says the two properties and the two sheds were lost in the blaze, in the Millingandi area, which has burnt 150 hectares.
There are 100 firefighters are on the ground, while three aircraft will work until nightfall to try to contain the blaze, which crossed the Princes Highway earlier on Friday and was impacting on local properties.
Residents were being advised to head north to Bega or South to Merimbula if they wished to leave the area.
No mandatory evacuation order has been put in place.
Meanwhile, a fire has broken out in Ku-ring-gai Chase National Park in north Sydney.
An RFS spokesman said the fire was not threatening any properties, but would be visible to those living in the northern suburbs.
A helicopter is assisting crews to contain the fire.
In the meantime, more than 50 fire trucks are trying to stop a big, fast grass fire that's threatening properties and heading towards Boorowa in southern New South Wales.
Emergency telephone warnings have been sent to residents,telling them leave if they are between the fire and Boorowa and it is safe to do so.
The fire was five kilometres south-west of the town just after 4pm and is moving quickly towards it in an easterly direction.
A water bomber is helping the ground crews and the air crane was on its way amid fears the blaze could reach the town's outskirts in a few hours.
