The Bureau of Meteorology said calls had increased by an unprecedented 1,200 percent in the past two days as the mercury in Sydney, Adelaide, Melbourne and Brisbane climbed.
"Australians tend to be obsessed by the weather, but I haven't seen the level of activity increase this much... it's unprecedented," Lara Thom, managing director of the company that hosts the bureau's weather services, told Reuters.
"On a normal day, it's in the thousands but now it's in the tens of thousands. It's possibly driven by the fact that four states have experienced almost heatwave-like conditions, and also we're going into the bush fire season."
The temperature in Adelaide touched 41.3 degrees Celsius (106 Fahrenheit) on Tuesday, according to the Bureau's website www.bom.gov.au, after reaching 35.2 degrees Celsius on Monday. On Wednesday, it was 27 degrees Celsius.
