At the start of the week, moist onshore southeasterly trade winds brought showers and moderate falls to the north tropical coast of Queensland. Isolated thunderstorms and showers developed in parts of the Kimberley and eastern Northern Territory along broad surface troughs situated over northern Australia. Further south, a cold front tracked across south west Western Australia and brought light falls to the southwest and southern coast of that State.
By the middle of the week, the cold front moved eastwards, crossing southern South Australia. A pre-frontal trough extended north, connecting to a broad trough across the Northern Territory and northern Western Australia. Isolated showers and thunderstorms were recorded in the Kimberley, and parts of the northern half of the Northern Territory. The cold front continued to track across southeast Australia, with moderate falls reported in southern Victoria, Tasmania, and elevated areas of the Snowy Mountains in New South Wales. Another cold front quickly followed and tracked across Tasmania, generating further light to moderate falls southern Victoria and western Tasmania.
At the end of the week, an upper-level trough generated an extensive cloud band with isolated thunderstorms over the Northern Territory and western Queensland. A broad area of low pressure over northern Western Australia generated isolated showers and thunderstorms in the Kimberley. Isolated thunderstorms also developed along the south east Queensland coast near a surface trough.
Rainfall totals in excess of 25mm were recorded on the north tropical coast of Queensland, south of the Gulf of Carpentaria and around the Darwin–Daly District in the Northern Territory, in places in the northern Kimberley in Western Australia, and in western Tasmania.

The highest weekly total was 85mm at Whyanbeel Valley on the north tropical coast of Queensland.
Weekly rainfall totals between 10mm and 50mm were recorded in the northern Kimberley, a coastal area to the south of Broome, and along the far southwest coast of Western Australia; far southeastern South Australia; southwest, southern central, and far northeastern Victoria; and in western and parts of northeastern Tasmania. Similar totals were recorded in a small area of the Snowy Mountains in New South Wales; around the southeast coast and north tropical coast of Queensland; and in parts of the northern half of the Northern Territory.
