WEEKLY rainfall totals over 300 mm were recorded along the northern New South Wales coast and Queensland’s Gold Coast, with daily totals exceeding annual and monthly records in many locations.
Weekly rainfall totals in excess of 150 mm were also recorded along the East Gippsland Coast in Victoria, along with totals exceeding 100 mm for parts of western Western Australia.
Heavy falls led to major riverine flooding for New South Wales’ Northern Rivers and Queensland’s Gold Coast, as well as localised flash flooding for other areas affected by significant rainfall.
Weekly totals greater than 50 mm were recorded in large parts of western Western Australia, along much of the south-east mainland coast and parts of Cape York in Queensland.
The highest weekly total was 530.3 mm at Mcleans Ridges (Lascott Drive), in the Northern Rivers District in New South Wales.
March rainfall was 27 percent below average for Australia as a whole.
Rainfall was below average for most of the Northern Territory, western and central parts of Queensland, western parts of Tasmania, and across much of South Australia’s Eyre Peninsula.
March rainfall was in the lowest 10pc of historical observations for the month (decile 10) for large parts of the northern Northern Territory, extending across the Queensland/Northern Territory border, in pockets along the central Queensland coast, and in south-west Tasmania.
Rainfall for March was above average for eastern New South Wales and parts of the Riverina and Lower Western districts; in south-east Queensland, the Wide Bay and Burnett, and Darling Downs districts; parts of Western Australia in the west of the state and the Kimberley extending into adjacent inland areas; much of Victoria, and parts of eastern Tasmania.
Rainfall was highest on record for March (since 1900) for areas of the central and northern New South Wales coast, leading to significant flooding throughout the month.
