Fire Bans In Place Ahead Of Tough Day For Firies

Firefighters are on high alert with hot, dry and windy conditions posing a risk to residents around the country.

Total fire bans are in place for seven areas across NSW, including Sydney, as the state heads into the first of two "tough days" this week.

Much of the east coast is under sever fire danger, with temperatures expected to climb into the 40s in some regions.

There is little-to-no rainfall forecast and winds are expected to reach 50 kilometres per hour.

Six lives and 530 homes have been lost since the state's bushfire season hit some weeks ago, with more than 420 properties destroyed in the past fortnight alone.

There are 51 grass and bush fires still burning around NSW, all of which are at "advice" level, with more than 1300 firefighters working through the night in a bid to contain dozens of blazes still out of control.

A poor air quality warning has been issued for Sydney with a thick blanket of smoke settling in over the city overnight.

The smoke haze isn't expected to clear until a southerly wind change arrives on Tuesday evening.

Fire-ravaged Queensland is bracing for similar conditions with the mercury set nudge 40 degrees as exhausted firefighters struggle to contain dozens of bushfires burning across the state.



Campers Forced To Flee As QLD Battles Blazes And Mops Up Storms

A resort has become a refuge for about 220 campers and holidaymakers forced to flee a bushfire on Moreton Island off southeast Queensland.

Conditions are expected to deteriorate further on Wednesday as hot winds sweep across the southern interior, according to the weather bureau.

The blazes of biggest concern are at Crows Nest, north of Toowoomba and a second in the Pechey State Forest, which has tripled in size forcing schools and businesses to close with reports up to five homes have been lost.

South Australia is also on fire watch with a total fire ban declared across the state ahead of what could be catastrophic fire conditions on Wednesday.

While the temperature in Adelaide is expected to hit 30C on Tuesday, the CFS said fire bans have been issued on Tuesday, because any blaze that breaks out is unlikely to be controlled during intense conditions on Wednesday.



Australia Braces For Heatwave As Temperatures, Fire Danger Set To Soar

A mid-week heatwave will see temperatures climb to 40 degrees and severe fire danger revived in parts of Australia.

It will reach 42C in Adelaide on Wednesday, 45C at Ceduna, 44C at Murray Bridge, Whyalla and Port Lincoln, and 43C at Port Pirie.

"We are putting restrictions on activities on Tuesday to minimise the risk of fires starting, which may not be fully extinguished by Wednesday," CFS chief officer Mark Jones said.

"A rekindled burn off on Wednesday would create dangerous conditions for our firefighters so we are not prepared to put them or the community at unnecessary risk."
