Vulnerable homeowners face a fight to discover food and somewhere dry to sleep when flood waters recede and momentary shelters shut.

Nearly 800 individuals have actually looked for sanctuary in NSW evacuation centres but their status as pop-up homes for some will cease to exist after the impact of Alfred passes.

Kim Kennedy, Vinnies' local housing and homelessness supervisor for northeast NSW, has actually been on the cutting edge supporting people sleeping rough in flooded zones.

Her job was made harder on Monday due to damage to Fred's Place, the Tweed Heads drop-in centre where she is based, with continuous rainfall flooding the space.

On any provided day, the centre serves about 130 hot meals to those in need but showers and laundry centers run out commission till the flood damage is fixed.

"It has actually been a horrendous time for the homeless neighborhood," Ms Kennedy informed AAP.

"It has actually been actually difficult trying to get them any type of shelter."

She said the homeless were trying to discover any dry locations they could sleep across a northern NSW area currently dealing with a dire shortage of inexpensive real estate.

"We have actually been assisting out a whole household sleeping in their vehicle," Ms Kennedy said.

"Seeing them in this horrendous weather is really dreadful."

The Byron Shire city government area, south of Tweed Heads, had the most rough sleepers of any council location in the state, according to a 2024 government street count.

"We definitely do have a housing issue in the Northern Rivers and we require solutions," Ms Kennedy said.

NSW Premier Chris Minns stated evacuation centres established in schools, universities, health clubs and clubs might not work as a long-term repair to established housing issues in the area.

"I am fully knowledgeable about the substantial challenges for real estate in the Northern Rivers, however evacuation centres are not long-term options ... we don't have the resources, the staffing, the time, the allocation," he stated.

The centres would close in all locations once regional emergency orders were lifted, Mr Minns added.

"So I want to apologise ahead of time but we need to draw an extremely clear and understood line."

More than 10,000 individuals were under emergency situation warnings in NSW on Monday early morning, while 1800 individuals were isolated by floodwaters.

About 10,000 homes and businesses were still not linked to power as heavy rain continued to fall in lots of locations.

Major flood cautions were still in location for parts of the Clarence and Richmond rivers, while clean-up operations were under way somewhere else.

In Pottsville, between Tweed Heads and Byron Bay, a whale carcass was among the debris that cleaned up after substantial swells damaged the coastline for days.

Residents from 17 NSW city government locations who had lost income due to the storm would be eligible for federal catastrophe relief funds for as much as 13 weeks, it was revealed on Monday.

Prime Minister Anthony Albanese stated the monetary assistance would be backed by psychological health services for affected areas.

"We've got your back, that's my message to communities here," he stated from Lismore on Monday.
