A five-year-old child is missing after being washed away in floodwaters in western New South Wales.
Two vehicles were trapped in the floodwaters on McGrane Way in Tullamore, north-west of Parkes, about 8 pm on Friday.
Emergency services rescued four people who were clinging to trees but were told the child had not been accounted for.
The vehicles are still submerged and the police are waiting to get access to them.
The situation is still evolving, according to forecasters, due to the menacing low-pressure system that brought torrential rain and flooded dozens of river systems.
Heavy falls in inland NSW and the state's north coast slowed on Friday, leading forecasters to cancel a severe weather warning as the low-pressure system began to move offshore.
The Bureau of Meteorology is closely monitoring rainfall and river heights, and this is an evolving situation, the BoM said on Friday.
Flood warnings remain active for 28 river systems from the inland west, through the northern rivers and the mid-north coast on Saturday.
More severe thunderstorms are predicted to dump more buckets of rain over the eastern coast on Saturday, as cells stretch from the Queensland border to the Blue Mountains, raising the risk of flash flooding, fallen powerlines, and dangerous driving conditions.
Flood warnings remain in place for the Tweed, Wilsons, Clarence, Bellinger, Nambucca, Macleay, Orara, Upper Macintyre, Macintyre, Gwydir, Peel, Namoi, Castlereagh, Macquarie, Bogan, Murrumbidgee, Murrumbidgee, Birrie, Bokhara, Narran, Warrego, Paroo, Darling and Upper Murray, Murray and Edward Rivers.
The Namoi River passed major flood levels in the town of Gunnedah, home to 9,000 people, reached the 7.9 metres mark late on Friday night and was expected to peak at 8.3 metres on Saturday morning.
At Wee Waa, just 120 km north-west, floodwaters peaked at the Namoi on Thursday, and were falling slowly, with the BoM predicting that they will remain above major flood levels until next week.
Narrabri Shire mayor Ron Campbell said that the rainfall has destroyed local roads because of Wee Waa, a cotton town, protected by an 8 km levee.
If we get substantial rainfall over the summer, we could have a record flood, for sure, something not seen since the 1970s, Campbell said.
The rain had caused a lot of anxiety for the Tweed River as locals saw the river burst its banks on their paddocks on Friday.
After major flooding hit the region earlier this year, many locals remained vigilant, said Harriet Messenger, co-owner of Husk Distillers.
She said that everyone in the region is very on edge, particularly close to another major event.
Farmers in north Queensland also had an anxious few days after heavy falls in the state s north, but a severe thunderstorm warning was cancelled on Friday.
Currumbin Valley organic farmer David Freeman suffered losses of his leafy green crops, and said he feared that the wild weather may have killed half of his avocado trees.
They are very sick as a result of the last 12 months of heavy rainfall because of saturated soil and this deluge is just going to re-saturate the soil and cause more soil fungus problems, Freeman said.
The rain is weighing heavily on farmers because they just got trashed in the early part of the year.
