Australia's tropical north experiences heavy rains during the monsoon season at this time of the year, but the recent downpour has surged far above normal levels, straitstimes.com reported,
Thousands of residents in the city of Townsville in Queensland were without power and cut off by flooded roads.
More severe weather could whip up tornadoes and destructive winds in the days ahead, Bureau of Meteorology state manager Bruce Gunn told reporters on Sunday.
"Atmospheric conditions are ripe for tornadoes and waterspouts around Townsville," the bureau said on Twitter.
"Damaging to destructive winds are possible in these intense storm cells."
Up to 20,000 homes are also at risk of being inundated if the rains continue.
Military personnel were delivering tens of thousands of sandbags to affected locals, as Queensland Premier Annastacia Palaszczuk warned residents to be careful.

"It's basically not just a one in 20-year event, it's a one in 100-year event," she told reporters on Saturday.
The Bureau of Meteorology said a slow-moving monsoonal trough was sitting above Queensland, with some areas expected to receive more than a year's worth of rain before conditions ease.
Bureau meteorologist Adam Blazak told AFP the heavy downpours could continue until Thursday, while floodwaters would take some time to recede even when the rains lessen.
The region receives an average of some 2,000 millimeters of rain annually but some towns were already on track to pass that.
According to the bureau, Townsville has already broken its record for the wettest seven days in a row, with 1,012 millimeters of rain falling by the end of Saturday compared to the previous record of 886 millimeters in 1998.
Meanwhile, the town of Ingham, north of Townsville, received 506 millimeters of rain in 24 hours between Saturday and Sunday, of which 145 millimeters fell in just one hour, Blazak said.
"I've never seen anything like this," Townsville resident Chris Brookehouse told national broadcaster ABC, adding that his house was flooded with water more than one meter deep.
"The volume of water is just incredible. Downstairs is gone, the fridge and freezer are floating. Another five or six steps and upstairs is gone too."
Blazak said that with adverse weather predicted to continue for up to 72 hours, some regions could see record-breaking levels of rainfall.
The national broadcaster ABC reported that thousands of homes had been abandoned in the suburbs of Townsville and that evacuations were being conducted.
There has been a silver lining to the deluge, with drought-stricken farmers in western Queensland welcoming the soaking.
"It is a welcome relief, especially in our western communities, to not only get the rain but also to fill up their dams," Palaszczuk said Sunday.
"We're getting food supplies in there. We still have many roads that are cut around those areas."
The deluge comes amid a severe drought in the eastern inland of the vast Australian continent, including parts of Queensland State, that's left graziers struggling to stay afloat.
Extreme heatwaves during the southern hemisphere summer have also led to maximum-temperature records being broken in some towns.
High temperatures are not unusual in Australia during its arid southern hemisphere summer, with bushfires a common occurrence.
But climate change has pushed up land and sea temperatures and led to more extremely hot days and severe fire seasons.
In the southern states of Victoria and Tasmania, firefighters in recent days have been battling numerous bushfires threatening homes and communities.
