More than 60 people face becoming homeless with the development the Gateway Caravan Park if the government doesn't act quickly, park owner John Igneneri says.
While Mr Igneneri doesn't shy away from the park's troubled reputation, he said there was more to it than met the eye.
"We know it is what it is - imagine trying to house 60 families, mostly on welfare, in the one place," he said.
"But we give people a home and a chance, people the government won't even give a chance.
"People rubbish this park, but for the residents, it's their home."
Mr Igneneri passionately defends his business, which he has owned for 30 years.
He said managing domestic disputes and mental health episodes was part and parcel of his role.
"If we called the police every time there was a blue they'd have to open a new station here," he said.
He works hard to keep the park safe for residents, and keep a roof over their heads.
When rent and electricity payments are overdue, he does his best to come to an agreement with residents.
"If you walk around and talk to some of the residents here, they'll tell you it's one of the only places they feel safe," he said.
"We have some very dysfunctional people here who can't just go out and get a job and live their life.
"They're going to struggle to deal with reality outside the park. Here, if they come to me and say they can't make rent because it was their daughter's birthday, I let it slide.
"I have tenants who are four months behind on rent. What other landlord would allow that?"
After 30 years owning the park, and 15 years running it, Mr Igneneri is looking forward to a quiet retirement with his family, and caring for his elderly mother.
"I'll spend the next few months getting to know my wife again and hopefully she still likes me," he said.
Now the park has beensold to Mosman property group he fears for the future of those who live there.
"I've looked after them for 30 years," he said.
"We get people referred here from the Homeless Hub and other organisations, because they know nowhere else will take them."
Julie Bugden, of the Shoalhaven Homeless Hub, confirmed the Hub often refers people to the Gateway Caravan Park when they have nowhere else to go.
"We've got a lot of clients that reside down there," she said.
"They use up their temporary accommodation, and private rentals are so scarce. Anyone on Newstart or Youth Allowance can't afford them, but they can get a caravan for $180-200 a week without a rental reference or credit rating.
"Where are they going to go? There's not enough private rentals or social housing, and our transitional housing is chock-a-block."
Mr Igneneri's park used to provide temporary accomodation for the state government, until the contract was cancelled due to Mr Igneneri's membership of the Rebels motorcycle club.
He is open about his Rebels' membership, but denied any wrongdoing.
"They tar me as a bikie caravan park - I've been a businessman for 40 years, I didn't just pop out a bikie," he said.
"You get good and bad in any organisation, and it's up to you who you mix with.
"I don't deal with drug dealers, assasins or anything like that. I don't deal drugs, I've never been to jail but they tar me with the same brush."
The length of time people are allowed to reside in caravan parks is limited, however Mr Igneneri said sometimes there was no option but to allow residents to stay.
"Do you expect us to throw them out in the street? They ask for help through housing and they don't get it," he said.
"If we had to turn them over every 140 days the showground would be full [of people sleeping rough].
"They need a helping hand to transition to their new life."
Mr Igneneri hopes the NSW Government will act before the park closes to ensure people living there have somewhere to go.
Kiama MP Gareth Ward confirmed the NSW Government no longer uses the Gateway Caravan Park for temporary accommodation.
He urged any person who is homeless or at risk of homelessness and requiring accommodation to call Link2home on 1800 152 152 and said the NSW Government is working hard to build more social housing in our region.
