According to the NSW Rural Fire Service website, there are 18 fires burning in the State, including two in the Shoalhaven area which are classified as major fires.

The rest of the NSW fires are under control, including one near Singleton in the Hunter Valley which spanned 3450 hectares.

Another at Wingecarribee, south-west of Sydney, burned 1132ha.

Of the two major blazes still burning in the Shoalhaven, one is in a remote area of Budawang National Park, approximately 30 kilometres north-west of Batemans Bay.

The RFS says the fire is burning on the south-eastern slopes of Mount Budawang and that no property is under threat at this time, despite already burning out more than 500ha of forest.

Six aircraft are currently being used to assist with containing the fire and National Parks and Wildlife Service crews are currently using heavy machinery to strengthen containment lines.

The second Shoalhaven fire is burning in a remote area of Morton National Park, 25km northwest of Nowra.

The fire has currently burnt approximately 7ha of forest and no properties are under threat at this stage.

National Parks and Wildlife Service Remote Area crews have been deployed by helicopter to construct containment lines.

Crews are undertaking slashing and earthworks on containment lines in preparation for backburning operations if conditions allow tonight.

Two water bombing aircraft are also assisting to slow the spread of the fire.

Meanwhile, Victoria's Country Fire Authority is monitoring five blazes, including one which may threaten the communities of Malmsbury and Taradale.

It reports that a fire at Drummond North in the Belltopper Forest is burning west of Malmsbury and moving in an easterly direction.

The CFA says the fire is spotting into rural land to the west of Malmsbury, and is expected to turn north towards Taradale with a change of wind later this afternoon shortly.

A grass and scrub fire near the Frankston-Dandenong Rd and Ballarto Rd Carrum Downs has subsided this afternoon having burnt 2ha.

A grass fire was also burning in Hallam, near the corner of David Lee Rd and Westpool Drive. It is under control having burnt 1ha.

Another grass fire burning approximately 15 kilometres north east of Camperdown, has also subsided, having burnt 1ha.
