Sydney is experiencing its hottest day on record, with temperatures reaching nearly 115 F (46 C).
A temperature of 114.4 F (45.8 C) was recorded at Observatory Hill in the Australian city at 14:55 local time.
Some areas in the wider Sydney region were even hotter, with the town of Penrith, to the west, registering a temperature of 115.7 F (46.5 C).
Firefighters are still battling dozens of wildfires sparked by the intense heat in New South Wales and Victoria.
The small town of Licola in eastern Victoria is reported to have been cut off by a 44,500-hectare fire, as its sole access road is blocked.
Officials said dozens of people had been evacuated but 10 locals were still there.
Rob Gilder, a sheep farmer, said he and two employees had found themselves trapped on their farm and were “in grave danger”.
He told the Herald Sun they were taking steps to protect their house and farm equipment, but that he was concerned for his livestock, and that the situation could worsen.
“I am very worried. But I am hopeful that one of those helicopters will come and get us but I think the smoke might beat them.”

Australia faces wildfires each year as temperatures climb. In February 2009, on what has come to be known as Black Saturday, 173 people were killed in fires in the state of Victoria.
On Friday, Prime Minister Julia Gillard attended a memorial service for fires in 2003 in the capital, Canberra, which killed four people and destroyed thousands of homes.
She reminded Australians to “take the appropriate precautions to stay safe and monitor information from local emergency services as they work to protect lives and property”, the AFP news agency reports.
The previous recorded high in Sydney was in January 1939, when the thermometer topped 113.5 F (45.3 C) at Observatory Hill.
The Bureau of Meteorology said in a statement that Friday’s record-setting temperatures “were not limited to Sydney, with records being set along the coast from Bega (44.6 °C) to Williamtown (44.8 °C)”.
“The highest temperature recorded in the Greater Sydney Area was 46.5 °C at Penrith, where observations started in 1995.”
Officials in Sydney have warned people to be ready for the heat, take care, avoid strenuous activity and stay out of the sun.
The heat has damaged wiring to urban railway lines, bringing delays to much of the network – CityRail have warned passengers to carry water with them.
The emergency services has received dozens of calls from people seeking help for heat-related health issues, including dizziness, fainting and vomiting, ABC News reports.
Chief Superintendent Ian Johns said elderly and ill people tended to suffer the most, but warned that “people underestimate the heat and overestimate their ability and that would be particularly so for younger, fitter Australians”.
The heatwave across Australia in recent weeks has been so intense that the Bureau of Meteorology has had to add a new shade to its color-coded temperature chart, so the scale now reaches above 122 F (50 C).
However, meteorologists have forecast a dramatic change in weather overnight in Sydney, with thunder storms expected to bring a rapid drop in temperatures.
Firefighters are battling a huge wildfire raging near the wealthy resort of Marbella on Spain’s Costa del Sol.
At least one person has died and thousands more have been evacuated.
The body of an elderly man was found near Ojen. Rescue workers are searching for his wife.

Firefighters are battling a huge wildfire raging near the wealthy resort of Marbella on Spain's Costa del Sol
Hundreds of firefighters, backed up by emergency military personnel and 31 planes and helicopters, continue to battle a huge blaze that is being fanned by hot, dry winds.
According to the AFP news agency, a 12 km (7 mile) line of fire has spread across the high tree tops in the Sierra Negra mountains.
In addition to the dead man, who was found near his home, five people have been treated for injuries, some of them serious.
Angel Nozal, the mayor of Mijas, a town between Marbella and Malaga, told El Pais newspaper: “The fire is horrific, with flames 10 to 15 metres high.”
The Costa del Sol is one of Spain’s most popular holiday destinations and home to a large expatriate community.
Much of Spain’s countryside was left tinder-dry this summer by a prolonged heatwave. There have been major wildfires in northern Catalonia – near the Pyrenees – and on La Gomera, in the Canary Islands.
Residents of Ojen described panic as the flames forced them to flee without time to gather belongings.
“We left just in our clothes, our nerves jangling,” said Filomena Gomez.
Evacuees from Ojen are now staying in a sports hall in Marbella.
The wind speed has dropped since Thursday and the air is more humid, so there are hopes that the Costa del Sol blaze can be contained soon.
The fire started on Thursday afternoon in the Sierra Negra area of Coin, near Malaga and has now affected an area of some 1,000 hectares (2,471 acres).
Part of the AP-7 highway was cut temporarily, but other roads are unaffected. It is not yet clear how many homes have been damaged or destroyed.
Two of the biggest ever wildfires in the US have hit states of Colorado and New Mexico and hundreds of firefighters have joined efforts to tackle them.
The Colorado blaze shrouded the state capital, Denver, some 60 miles (100 km) away in smoke on Tuesday.
A woman has died in the blaze, which has burned about 43,000 acres (68 sq miles) and is still growing.
A huge fire is also burning in New Mexico – one of a total of 19 fires in nine drought-stricken western states.
The Larimer County Sheriff’s Office said on Monday that one person had died in Colorado, after investigators found remains in a home that had been burned in the fire.

Although the remains have not been conclusively identified, the family of Linda Steadman, 62, has issued a statement saying she died in a cabin that she loved.
They reported her missing after the fire started on Saturday, sheriff’s officials said.
President Barack Obama called the Colorado governor to offer federal personnel, equipment and emergency grants – but was unable to reach his New Mexico counterpart due to poor reception in the fire zone, the Associated Press reported.
The High Park Fire – as it has been dubbed – is still growing, with only 5% contained, reported a national incident information website.
The same website says 30% of the 36,000-acre (56-sq-mile) Little Bear Fire in New Mexico has been contained.
About 118 structures have been damaged or destroyed by the blaze in Colorado – believed to have been started by lightning – and hundreds of people were forced to evacuate, officials say.
Some 600 firefighters are on the scene and up to 200 more are expected.
Additional resources have had to be called in as state and federal authorities rushed to tackle the blaze.
The US Forest Service said on Monday it would contract one air tanker from Alaska and four from Canada to add to the aircraft already combating the fire. Two more air tankers were also being mobilized in California.
Five of the forest service’s 13 tankers have already been deployed to the scene, a spokesman said.
Congressmen from Colorado said in a letter to the forest service that the need for more aircraft was “dire”.
But incident commander Bill Hahnenberg told the Associated Press: “We are a very high priority nationally. We can get all the resources we want and need.”
