Australian authorities have issued heatwave warnings for most of the country as millions celebrate Australia Day.
Temperatures are expected to peak on Tuesday, reaching the “high forties” Celsius in the southern states of Victoria and South Australia, the Bureau of Meteorology said.
On Sunday, South Australia recorded temperatures as high as 48.5C, according to the bureau, which is warning of fire danger in parts of the country.
Some national day celebrations on Monday have been cancelled out of safety concerns.
In Adelaide, an Australia Day parade and light show have been cancelled due to the extreme heat forecast.
“While this is deeply disappointing for the community, performers and partners, community safety and wellbeing must come first,” organisers said.
Australia Day – 26 January – is the anniversary of the 1788 landing of Britain’s First Fleet, which began the era of colonisation.
But to many Indigenous Australians the occasion is a reminder of their cultural destruction under European settlers – referring to the occasion as “Invasion Day”.
Across the country on Monday, crowds gathered for rallies in support of Indigenous Australians.
Aside from Victoria and South Australia, heatwave warnings have also been issued in New South Wales, Queensland, Tasmania, Northern Territory and the Australian Capital Territory.
Many of these warnings will remain in place until Wednesday.
“We haven’t seen heatwave conditions like this in Victoria for almost 20 years,” Tim Wiebusch, Victoria’s emergency management commissioner, told ABC.
“It was 2009 ahead of the bushfires where we saw those prevailing conditions and so we are indicating to all Victorians that this is a very serious set of weather conditions.”
On Monday, the Bureau of Meteorology warned of “extreme fire dangers” across parts of South Australia and much of south-western Victoria “due to very hot and dry weather combined with moderate to gusty winds”.
Firefighters in Victoria are working to combat several fires across the state, which have prompted evacuations and threatened properties.
The heat has also affected the Australian Open at Melbourne Park. Tennis player Jannik Sinner was seen suffering from cramps on the court on Saturday, before play was temporarily suspended in the rising heat. Nearly 80,000 fans were warned to take care under the scorching sun.
Meanwhile, parts of Western Australia were pummelled by Tropical Cyclone Luana over the weekend. The storm damaged homes and a popular beach resort before weakening as it moved inland.
The meteorological bureau has advised people to find places to keep cool, like their homes, libraries, community centres or shopping centres. It also told people to close their windows and draw the curtains to keep heat out of their homes.
