RAINFALL for the past week fell in the south-west of Western Australia, south east Victoria, Tasmania, parts of eastern New South Wales, and central inland Queensland.

From the middle of the week, a pair of cold fronts tracked over Tasmania, generating moderate falls in the state’s west and north-east, and light falls across southern Victoria.

Towards the end of the week, a surface trough extending through inland Queensland triggered showers and thunderstorms over the Central Highlands District.
