The biggest falls were again dropped on storm-savaged Brisbane and its surrounds, but big readings have also been taken on the Darling Downs and in northern NSW.

According to The Weather Company, cloud is today lingering over southeast Queensland, eastern NSW, Victoria and Tasmania in a trough that is causing isolated showers.

But there is thick cloud over the eastern interior in another trough, which is generating heavy, squally thunderstorms, while cloud over South Australia in a weakening trough is also causing showers, mainly inland.

In SA, the Bureau of Meteorology reports that the best falls were in the north and remote parts of the State, with Andamooka recording 13mm, Mt Eba 25mm, Roxby Downs 15mm, Woomera 21mm, Bruce 12mm, Hawker 20mm, Pt Augusta 10mm, Maree 20mm, Moomba 15mm.

Just north of the border Alice Springs has recorded 48mm.

That outback rain has also delivered for Queensland with the Bureau reporting Barcaldine receiving 14mm, Toomba 43mm, and Richmond 26mm, while in the far north Babinda received 18mm, Mareeba 37mm, and Port Douglas 80mm.

But the rain is also threatening harvest in areas like Moree which received 27mm, while Gunnedah scored 45mm, Breeza 58mm, Tambar Springs 59mm, Baradine 68mm, Burren Junction 29mm, Binnaway 42mm, Walgett 19mm, Narromine 28mm, Gulargambone 56mm, Coonamble 71mm, Condobolin 30mm, and Dubbo 38mm.
