Australians will remain hot and bothered for this week as heatwave conditions push temperatures into the mid- 40s in some regions around the country.

 

The Bureau of Meteorology has forecast daytime temperatures of up to 12C above average and 10C higher than usual at night from Monday to Friday.

 

An extreme heatwave is expected to sizzle across most of eastern NSW this week while the rest of the state will experience severe conditions.
