On September 12-13, a cold front and the associated trough moved across parts of southern Australia generating light to moderate rainfall.

Weekly rainfall totals of 10-25mm were recorded in small areas in the far south-west of WA, north-western Victoria and adjacent parts of New South Wales, and much of western Tasmania.

Throughout the week, a high-pressure system directed moist onshore flow to the east coast of Australia.

Weekly rainfall totals of 10-50mm were recorded in small areas of coastal Queensland and northern NSW.
