Flooding in New South Wales has predominately been caused by excessive flows into rivers located in New South Wales and, to a lesser extent, excessive flows into rivers located in Queensland and Victoria. Floods can devastate local communities and impact the entire local economy. The principal topographic feature of New South Wales is the series of low highlands and plateaus called the Great Dividing Range, which extend from north to south roughly parallel to the coast of the Coral and Tasman seas of the South Pacific Ocean. Flooding occurs both west and east of the Range, although the prevalence and impact of flooding of rivers that flow easterly towards the coast is more pronounced due to larger flows of water and high population levels. The principal meteorological cause of flooding is the Australian east coast low.
