More than 16,000 head of livestock have been reported lost or missing as Queensland's north braces for further rainfall and river levels continue to rise.

Townsville copped the brunt of the rainfall overnight with more than 200mm recorded in the 24 hours to 9am as the system moved over the state's north-east coast after dumping more than a metre of rain in some areas of the north-west over the last few days.

Two people narrowly escaped their vehicle as it sunk into fast-moving floodwater at Cape York Peninsula while a man was winched from his motorhome by rescue crews at Dimbulah west of Cairns.

The state government's current estimate of around 16,450 head of cattle reported lost or missing, as well as hundreds of kilometres of fencing and roads and crucial equipment could still increase when floodwaters recede.

The low-pressure system will move north towards Cape York Peninsula from tomorrow, but flooded communities are bracing for rivers to continue to rise.

Meteorologist Miriam Bradbury from the Bureau of Meteorology said there was currently flooding across western and northern parts of Queensland, pushing towards the north-east coast.

"Even in these places where the rain might start to ease off, we will continue to see riverine flooding," she said.

"We are currently seeing major flooding occurring on the Flinders River at Richmond and Walker's Bend, and on the Western River at Winton.

"We may also see possible further rises with the arrival of upstream flows."

Flood warnings are currently in place for the Georgina, Norman, Gilbert, Nicholson, Leichhardt, Herbert, Western, Diamantina, Tully, Burdekin, Cape, Flinders, Cloncurry and Bohle rivers as well as Eyre Creek.

A tropical low is also tipped to form off the coastline from tomorrow.

People are urged to stay up to date on the BoM website and the Queensland government's disaster website.

Premier David Crisafulli announced disaster relief for the affected areas last week.

Capital cities across the country could suffer through sizzling temperatures of more than 40 degrees this week as a heatwave sweeps across Australia's eastern states.

Intense heat has built up over Western Australia, leading to extreme heat in the state, but this is set to move east in the coming days, Weatherzone said.

The hot airmass is expected to hit South Australia and Victoria by Wednesday, bringing top temperatures of 41 degrees to Adelaide and Melbourne.

It reached the low 40s by 11am in parts of in-land WA today.

Similarly hot temperatures are moving across the country to the east, as far as south-west Queensland.

The Bureau of Meteorology has warned that there will be a three-day period where the extreme heat will hit its peak, between Wednesday and Friday this week.

"We're likely to see extreme heatwave conditions over a huge part of NSW and northern Victoria, practically everywhere between Melbourne and Sydney, and extending well in-land," said meteorologist Dean Narramore.

Weatherzone's Tim Woebbeking said Wednesday will be the warmest day for multiple cities, particularly for Adelaide and Melbourne.

"While Wednesday stands out as the hottest day of the week for both Adelaide and Melbourne, there is a chance that Adelaide could reach 40 degrees again on Thursday with the hot air mass expected to linger over SA's south," Woebbeking said.

The hot weather will reach Melbourne on Thursday and Friday, with maximum temperatures of 30 degrees and 35 degrees respectively.

Thursday could bring some relief for coastal areas within 10 to 20 kilometres of the ocean due to a southerly wind.

However it is expected to remain a sweltering day across in-land SA, NSW and Victoria.

It will be even hotter in Adelaide, with Thursday peaking at 39 degrees, while Friday is forecast to reach 38 degrees.

The hot air will make its way to New South Wales later in the week, with Sydney not escaping the heat.

Although the harbour city won't see temperatures hit 40 degrees, there will be four days of heat beginning on Wednesday, with the mercury peaking on Saturday at 36 degrees.

However, showers on Sunday will drop temperatures below 30 degrees, with up to five millimetres of rainfall expected.
