'It's too late to leave' for residents under threat from fire near Sydney

Blazes continue to rage on either side of the country as an emergency warning has been issued for a fire northwest of Sydney and firefighters in Western Australia save more than 6000 homes.

Residents in the path of a major blaze in the Wollemi National Park, northwest of Sydney, have been told it's too late to leave as the fire pushes closer to their homes.

An emergency warning was issued for the Gospers Mountain blaze, which is almost 370,000 hectares in size, on Sunday afternoon.

The NSW Rural Fire Service says the fire has crossed Bowen Creek, south of Mount Wilson.

The blaze is moving towards Mount Wilson, Mount Irvine, Mount Tomah and Berambing, and winds are creating spot fires ahead of the main fire front.

For residents in these areas the RFS advises fire activity is increasing.

"It is too late to leave. Seek shelter as the fire approaches. Protect yourself from the heat of the fire," the RFS said in a statement on Sunday afternoon.

"This large fire stretches from the Lithgow area in the west, through the Hawkesbury area and towards the Central Coast in the east.”

At 8.30am on Sunday there were 106 bush and grass fires burning around the state with 57 not yet contained.

"With many areas of the state under a Very High fire danger today, discuss with your family what you would do if fire threatens," the RFS posted on Twitter on Sunday morning.

Total fire bans are in place for the Central Ranges, Northern Slopes and North Western areas amid very high fire danger ratings on Sunday and more bushfire smoke will affect the Sydney Basin.

Some 1500 firefighters were tackling the blazes on Saturday night and there was no let-up on the horizon, Greg Allan, from the RFS, said.

"We will see conditions deteriorate with worsening weather early into mid-next week. We're going to be seeing a lot more higher temperatures across the state," he told AAP.

Places such as Cobar, Broken Hill and Griffith will see temperatures above 40C in the coming week, the Bureau of Meteorology said.

Some 724 homes, 49 facilities and 1582 outbuildings had been destroyed so far this fire season. Six people have died and 2.7 million hectares have been scorched.

Homes still at risk from West Australian blaze

Thousands of properties have been saved from a bushfire raging out of control north of Perth, but authorities say the threat isn't over.

The Yanchep blaze remains at an emergency warning after firefighters protected more than 6000 homes from the near-12,000 hectare blaze.

One house and a Yanchep service station are confirmed to have been lost.

"If you look at where the fires have gone, it is absolutely astonishing that we haven't lost more than one house," Emergency Services Minister Fran Logan told reporters on Sunday.

But communities are warned to remain vigilant, with Perth and the fire area forecast to reach 40C for the third day running.

Lives and properties are under threat at Guilderton, Woodridge, Gabbadah, Wilbinga, Caraban, Seabird, Yeal, Redfield Park, Soverign Hill, Seatreets and Breakwater Estates.

Parts of Two Rocks, Neergabby, Yanchep, Gnangara-Moore River State Forest, Moore River National Park and the Yeal Nature Preserve are also covered by the warning.

A watch and act warning is in place for parts of Yanchep, Two Rocks, Breton Bay, Seabird, as well as parts of Gabbadah, Wanerie, Ledge Point and Eglinton.

Emergency services said firefighters have saved more than 6000 homes in the area.

"[It's] reasonably calm at the moment," Department of Fire and Emergency Services Commissioner Darren Klemm said, but said the threat had not passed.

Evacuation centres have been set up at the Gumblossom Community Centre at Quinns Rocks and the Granville Civic Centre at Gingin where a community meeting was to be held on Sunday.

Four schools – Two Rocks Primary School, Yanchep Primary School, Yanchep Beach Primary School and Yanchep Secondary College – will be closed on Monday.

Nearly 260 Two Rocks households have lost power and it's unclear when it will be safe to repair the network.

Internet and mobile phone services have been disrupted at Two Rocks and Yanchep.

Another emergency warning remains in place for a separate blaze at Yourdamung Lake, northeast of Bunbury.
