The Bureau of Meteorology released their long-range forecast, predicting an increased risk of widespread flooding for eastern and northern Australia and an increased risk of an above-average number of tropical cyclones and tropical lows.
This season we have a greater than 70 per cent chance of at least 11 tropical cyclones, according to BOM.
After BOM declared a third La Nina event last month, communities are urged to prepare for an increased chance of tropical cyclones coming early.
After a week of rain that drenched large parts of NSW, Queensland, ACT, Victoria and Tasmania, already-flooded regions are set to face more wet weather later this week.
"The most significant rain weather will be the widespread rain across south-eastern Australia between Wednesday and Friday, which will lead to further flooding," Weatherzone meteorologist Brett Dutschk said.
The rainfall will put more rivers into major flooding, with some chance of properties being inundated, Mr Dutschk said.
"Take advantage of this short, dry spell - it would be wise to clear around your property," he said.
NSW, Victoria and Tasmania are set to bear the brunt of this week's severe weather.
NSW and the ACT
NSW faced flooding rains last week that severely affected the western and southern regions of the state, including Dubbo, Forbes, Wagga and Warren.
NSW SES volunteers received more than 1000 calls for assistance over the weekend, and conducted 44 flood rescues, including a man and three children who were rescued by helicopter from the roof of a car near Bowral.

NSW SES Assistant Commissioner Sean Kearns said the threat of flooding is not over yet.
"The next few days may be deceiving for NSW communities as we see some fine weather emerge across the state," Assistant Commissioner Kearns said.
"The water that has fallen over the last month is still travelling through our river systems and as the water travels downstream we have an increased risk of flooding in those areas."
Victoria
Parts of Victoria will likely face the heaviest rainfall this week, Mr Dutschk said, with the potential for up to 200mm over the state's high country in less than a 48-hour period.
A significant amount of rain will be coming down the mountain rivers and into the low-lying areas, Mr Dutschk said, which will also cause much of the alps' remaining snow to melt, adding to run-off.
Several flood warnings are current in Victoria, including a major flood warning for the Loddon River.
Tasmania
Northern Tasmania is set to face heavy rainfall between Wednesday and Friday, with up to 100mm expected in some parts.
The Bureau of Meteorology issued final flood warnings for several rivers in Tasmania, including the Meander River, Mersey and North Esk.
