"It's not just a one-off day of heat, the sort of heat on its own wouldn't be a worry for most people but its been a spell of building heat and it's probably starting to take its toll for some people," meteorologist from Weatherzone Brett Dutschke told nine.com.au.

Elsewhere, parts of Queensland are also expected to swelter while a new wave of heat begins in Western Australia.

"Those temperatures will be as much as 10C or 11C above average, so it's noticeably hotter than normal."

"Given that it's likely to 35C today, it'll be a maximum average of at least 33C for the last five days and that's effectively going to be the hottest spell in ten years."

The temperatures come amid large Invasion Day rallies expected to take place in Sydney despite limits on public gatherings due to COVID-19.

Penrith was 40C yesterday, looking to be 41C today. Richmond and Campbelltown are among many of the places are likely to get into the forties, along with much of northern NSW.

"This heatwave its losing intensity and from here on its just going to be confined to northern NSW and Western Queensland for the next few days and become low intensity whereas in Western Australia, there's a heatwave just beginning in the north west of the state and that will extend down parts of the west coast over the next several days," Mr Dutschke said.

Perth is likely to dodge the extreme conditions this week however next weekend could bring temperatures well into the mid to high thirties.
