Repair funds after 'gruelling' NSW floods

Flood-stricken regional communities across NSW will be given more cash to fix up damaged roads, and assisted with on-the-ground counselling services, as inland towns reel from historic flooding.

NSW Premier Dominic Perrottet said flooding in Condobolin had been worse than historic peaks seen in 1952, as he visited the central west town on Friday.

The premier had spoken with NSW Treasurer Matt Kean and Regional Roads Minister Sam Farraway, to shore up funding to repair vital regional roads.

"Flood event after flood event has made this an incredibly challenging task," he told reporters.

"But we will be allocating the funding required to make sure we get our communities back on their feet as quickly as possible."

Some 10,000km of roads have been battered by the floods, which the premier marked as a priority for his coalition government on Thursday.

Last Friday, eight central west and western NSW councils received a combined $15 million to begin road repairs and reconnect devastated towns.

Six Lifeline counsellors will be dispatched to the central west to provide mental health care to people affected by destruction, the premier said.

"It has been a very difficult time for everybody," Mr Perrottet said.

"It has been gruelling. There are many people who are tired, exhausted, emotional.

"It is a long journey ahead."

Farmers, who had recently been through droughts, were now under particular strain by the continued flooding, he added.

Insurers estimate the ongoing flood crisis in NSW is Australia's most expensive natural disaster after receiving about $5.5 billion in claims.

Major flooding is continuing in other parts of the central west, including at Euabalong, where the Lachlan River also peaked higher than the 1952 level on Friday.

The NSW Emergency Service has teams deployed into Euabalong, along with emergency crews from New Zealand, and Singaporean Civil Defence Force personnel.

SES deputy commissioner Dean Storey said resources were being focused on towns including Condobolin and Euabalong along the Lachlan River, Bourke on the Darling River, and Deniliquin and Moulamein on the Edward River.

The SES had liaised with the community of Euabalong ahead of the major flood and would keep resupplying essential goods and medication while residents remained isolated.

Residents can return to Condobolin with caution.

The Bureau of Meteorology says major flooding from the Murray River is occurring at Wakool Junction, Boundary Bend and Euston - all cross-border towns with Victoria.

In Bourke, major flooding has also occurred The Barwon-Darling river flood peak rose above the 1998 flood record but didn't breach the town's levee on Thursday night.

The Murrumbidgee River at Balranald Weir is also heading towards a 7.3m peak.

The bureau warns summer will be soggy, with more rain and inevitable flooding yet again.

It said December to February rainfall was likely - a greater than 60 per cent chance - to be above average for the north coast and southern NSW.
