Early in the week, severe thunderstorms and locally heavy rainfall were triggered by persistent low-pressure troughs extending from the north of Western Australia, through the interior into south-eastern Australia, before moving eastward over Queensland and New South Wales, leading to minor and moderate flood warnings issued for southern Queensland and northern New South Wales.

A deep low-pressure system with an associated cold front and low-pressure trough on 26 November brought rain and widespread storms to central, southern and south-eastern areas of the country.

A low-pressure system and trough developed over south-eastern Australia on 29 November to 1 December bringing widespread rainfall and heavy falls across New South Wales, Victoria and Tasmania, leading localised flood warnings in Tasmania.

A cold front and low-pressure trough on 1 December moved across south-west Australia, bringing scattered rainfall and storms to Western Australia, South Australia and southern Northern Territory.

Weekly rainfall totals greater than 25 mm were recorded for most of eastern and northern Australia and in parts of South Australia and southern Western Australia.

Weekly rainfall totals of 50 to 100 mm were recorded in areas of north-west Western Australia, eastern and southern regions of Victoria, and large parts of the Northern Territory, Queensland, New South Wales and Tasmania.

Weekly rainfall totals of more than 100 mm were recorded in parts of south-eastern and central Queensland, northern and south-eastern New South Wales, north-eastern Victoria, northern Tasmania and the Top End of the Northern Territory.

The highest weekly total (at a Bureau gauge) was 316.0 mm at Springbrook Road in Queensland, which included the highest daily total rainfall of 227.0 mm in 24 hours to 9 am on 1 December.
