A low-pressure system swept across south-west WA from 25 May and then through the Australian Bight, and reinforced cool, unstable, and showery weather with strong westerly winds and large waves across southern coastline.

The front moved across South Australia and Victoria delivering moderate amount of rain on 27th.

A surface low pressure system developed over coastal NSW and brough heavy falls in the Hunter, Illawarra and southern Tableland districts leading to the weekend.

Weekly totals greater than 50 mm were recorded in southeast and coastal NSW, and pockets of Cape York Peninsula in QlD, the NT Top End and south-west WA.

The highest weekly total (at a Bureau gauge) was 214.0 mm at Jervis Bay, NSW, where it also had the highest daily total of 207.2 mm to 9am on 30 April.
