It signalled a soggy and turbulent beginning to the week.
Severe damages were reported in coastal and inland centers, particularly Townsville, Cardwell and Ingham.
Areas affected by flooding are advised to stay informed about the latest weather updates as there is a possibility of additional rainfall in the region.
The Australian Bureau of Meteorology is predicting severe thunderstorms from Dubbo to Wagga Wagga and Albury-Wodonga, which is situated on the border of New South Wales and Victoria.
A senior meteorologist, Dean Narramore, forecasted that the extreme weather was anticipated to hit from Sunday afternoon.
He stated on Sunday that we might see intense thunderstorms with substantial hail, destructive winds, and heavy rainfall, potentially causing rapid flooding of businesses, roads, and property.
We could also experience hazardous driving conditions and damage to houses, properties, and companies during these storms, with fallen trees and downed power lines, especially due to strong gusts.
Significantly severe storms are anticipated to intensify on Monday across a substantial part of New South Wales' inland region and northeast Victoria.
'Falling totals of 25 to 50mm have been observed in eastern areas of Victoria and large parts of central and eastern NSW,' Mr Narramore stated.
We could see even heavier falls in excess of 100mm possible in parts of eastern Victoria, especially in central and southern areas of New South Wales.
In Queensland, major flood warnings have been issued for the Herbert, Burdekin, Haughton, Flinders, Cape, and Western Rivers. There are minor to moderate flood warnings in place for various other catchments in the northern and eastern inland regions.
Senior meteorologist Myriam Bradbury stated that 24-hour rainfall totals could reach upwards of 250 millimeters.
"The rain falling onto the already saturated ground is going to run off rapidly and increase the levels of the overflowing rivers," she explained.
'This indicates that even moderate rainfall amounts can quickly cause rivers to overflow and lead to hazardous flooded conditions.'
Emergency flood warnings are issued as communities in Western Australia's northern regions are on high alert for a potential tropical cyclone.
Forecasters have warned that the low-pressure system off the north Kimberley coast may intensify and become a cyclone by Monday.
By Sunday morning, the cyclone was situated approximately 237 miles west of Broome and 99 miles north northwest of Kuri Bay.
'The low is forecast to move southwest off the Kimberley coast and develop, potentially reaching cyclone intensity on Monday,' the bureau stated.
Gusty winds of up to 100 kilometres per hour were forecast along the coast between Cockatoo Island and Beagle Bay by Monday afternoon, potentially spreading further towards Broome and Bidyadanga.
Heavy rain on Sunday was also possible between Broome and Cockatoo Island.
Heavy rainfall in Queensland over the past week has necessitated the evacuation of hundreds of people from their residences and left many communities without access to electricity.
A major bridge in the town of Ingham was swept away, prompting the Australian Defence Force to deploy troops to establish a temporary route for vital shipments.
Some residents have begun reclaiming their homes that were severely damaged by the flood, with over 4,000 storm and flood-related insurance claims filed thus far.
The extent of the damage has yet to be determined.
So far, eight million dollars is available to those affected through the Commonwealth's community relief fund. Queensland Premier David Crisafulli is pushing for federal assistance to build bridges above flood level along the Bruce Highway.
The Chief Executive of the Queensland Reconstruction Authority, Jake Ellwood, cautioned that the clean-up would be a challenging task, with a significant strain on the mental wellbeing of those affected anticipated, in addition to physical and economic impacts.
'Short-term recovery and reconstruction is not a days and weeks event, it's a months and years process,' a retired Major General stated to reporters in Townsville on Saturday.
