Furious residents reeling from the deadly NSW bushfires have confronted Prime Minister Scott Morrison as anger boiled over in one of the towns hardest hit by the crisis.

As a state of emergency is declared for NSW and residents who've already lost friends and family in the fires await news of whether their homes are still standing, the PM visited evacuation centres to offer his support.

But while he was welcomed by some evacuees, his visit to the NSW Bega Valley town of Cobargo was cut short after locals told Mr Morrison "you should be ashamed of yourself". 

One local woman, in tears, refused to shake his hand until the PM offered more support to volunteer rural firefighters before.

"I am only shaking your hand if you give more money to the RFS. So many people have lost their homes," she said after Mr Morrison took her hand.

Another man, who locals identified as a former mayor and National Party member, Bega Valley councillor Tony Allen, then put his arms around the woman to comfort her and said "shush". The Prime Minister then turned his back to talk to another man in the crowd.

She then shouted after the Prime Minister, "We need more help!." as Mr Allen replied, "We know that."

As the scene turned ugly, a group of men and women shouted at Mr Morrison, telling him he was "an idiot."

"You won't be getting any votes down here, buddy," one resident yelled.

"Who votes Liberal around here? Nobody.You are out, son, you are out! Go on, piss off."

As the abuse continued, the Prime Minister retreated to a white car as a local man yelled, "you're not welcome" and "go back to Kirribilli."

A woman holding a goat on a lead then complained the town wasn't getting enough help.

"This is not fair. We are totally forgotten down here. Every single time this area gets a flood or a fire we get nothing," she said.

As the Prime Minister's car exited the town, residents cheered and yelled, "Ya scumbag!".

Two local farmers, Patrick Salway and his 63-year-old father, Robert Salway, were discovered dead at their property near the town earlier this week after battling to save their home.

After Thursday's confrontation, Mr Morrison was interviewed by an ABC reporter who said: "You have been welcomed in many parts, not so welcome at the show grounds. Some people felt you let them down."

Mr Morrison replied: "In every circumstance, everyone understands that. I appreciate the welcome we received, Jenny and I but, at the same time, I understand the deep feelings.

"There are dangerous days ahead and we understand that. That's why we'll do everything we can to ensure they have the support they need."

It is understood that the bodies of the Salway men were found by Mr Salway's wife, Renee, who is expecting the couple's second child.

“I love you now, I love you still, I always have and I always will,” Renee Salway said on Tuesday night.

“I will see you again Patrick, my best friend. Hope you are up there ‘fixing things in the stars tonight’.”

Meanwhile, tourists are making their way back to Canberra, Sydney and Melbourne as huge traffic jams clogged the coastal roads after authorities urged them to "get out" before Saturday's catastrophic conditions.

"These will be dangerous conditions, the same or worse than New Year’s Eve," the RFS said.

"If you are holidaying in the Shoalhaven region, particularly in the areas identified on the map, you need to leave before Saturday. Residents within this area should be aware and prepare for the worsening fire conditions on Saturday."

The areas where tourists and residents are being urged to flee now include the Snowy Mountains, from Hyams Beach down to the far south coast near the Victorian border, and the town of Batlow which authorities have warned they cannot defend.
