Bill Eger on Monday said he was ashamed to be an Australian.
Mr Eger, a Rural Fire Service (RFS) firefighter, was not happy to see a fence get placed around a sensitive piece of land he and many members of the Manyana community are trying to protect.
It's one of the last blocks of its kind left unburnt from the brutal summer bushfires.
He is appalled by the whole situation and the passion in his voice echoes his frustration.
"We have already seen numerous wildlife injured," he said, as he watched another part of the fence put in place.
"We know there are 510 species in there and we also know many are critically engaged."
He wanted to know why an ecologist was not on the site.
"I have spoken to Shoalhaven City Council about it and we are really concerned there is not an ecologist on site," he said.
He said species like the greater glider will suffer once the bulldozer comes in.
"These animals don't have anywhere to go - there is no food anywhere else for them," he said.
"This is the last piece of ground that has an incredible number of habitat left."
He called on the politicians to act.
"We can't understand why federal minister for the environment Sussan Ley doesn't say 'hey just stop'," he said.
"What sort of a country are we living in when people can come in and destroy endangered species like that."
Mr Eger likes to think there is still hope but many of fellow Manyana Matters campaigners see the fence construction as a sad day for the area.
The community members did what they could to make things hard for the workers putting up the fence.
They parked cars close to the fence line and stood in places where part of the fence was being built.
A security guard was on-site and a police van drove past at one point in the morning.
"It's looking pretty dire now and once they get this fence up, they will move in with their excavators and tractors and will start knocking all these habitat trees downs, running over animals and all the rest of it," Mr Eger said.
He stressed again part of the developer's compliance agreement was to have an ecologist on site.
"We don't blame the worker here to tell you the truth, but these guys aren't wildlife experts or ecologists," he said.
"We need to keep an eye out on the wildlife running around in there."
Manyana Matters will continue to apply pressure to the politician making the laws and make them act.
"What I see here is criminal - it's disgusting," he said.
"It's an act of bastardy."
Mr Eger, in his role with the RFS, knows the devastation caused by this summer's bushfire.
"You walk out into the bush now and there is no noise - there is no sound of life anywhere," he said.
"There are species in this block that found nowhere else and we have had that confirmed."
He is "totally ashamed to be an Australian at the moment".
