Parts of Australia drenched by an eastern deluge are expected to be hit by more rain as floodwaters threaten to cut off a coastal town.

Eastern Victoria and southern NSW were bracing for more rain overnight after some areas recorded more than 150mm over 24 hours.

Kameruka Estate near Bega recorded 200mm of rain in 24 hours as of Thursday evening, while Mallacoota over the Victorian border - where a landslide earlier cut off the town - registered 112mm.

The Bureau of Meteorology warned a low pressure system would start moving further away from the coastline from today but rain would continue to fall on waterlogged areas into the weekend.

Rain was expected to hit soaked parts of Victoria for the next day or two, with some areas of the state's east expected to record falls of 200mm.

Several flood warnings were in place in Victoria as of Thursday night, with major alerts for the Thomson River, the Genoa River, the Buchan River, the Macalister River and the Bemm River.

The Bemm River was expected to peak by Friday afternoon and if it did flood, access to the community would be cut, an SES spokesman said.

Moderate flood warnings were in place for the Cann River and the Snowy River downstream of McKillops Bridge.

A severe weather warning was in effect for heavy rainfall and damaging winds for parts of East Gippsland, as well as the northeast, west and South Gippsland forecast districts as of Thursday.

Several advice-level flood warnings were in place for NSW, with some southeastern parts of the state expected to record up to 300mm of rain by the end of Friday.

A severe weather warning for heavy rainfall for people in parts of the south coast and Snowy Mountains remained in place on Thursday night before conditions were expected to ease.

The bureau warned flooding could persist after rain subsided in NSW and Victoria.
