Prospector Mike Fitzgerald, who complained about a load of rubbish dumped at Ophir last week including needles, used nappies and other rubbish, said he'd since heard from others who had seen or had to deal with rubbish in parks and spaces around the region.

Mr Fitzgerald said he'd been told rubbish was regularly dumped in Kinross State Forest, around Mount Canobolas and towards Mullion Creek.

He said something had to be done, and suggested signs - or, if possible, security cameras - at Ophir could deter people.

Mr Fitzgerald has been prospecting at Ophir in his spare time for nearly 30 years.

"If there are signs at either end of the gates at Ophir warning people about security cameras, people might think twicew about it if there's surveillance," he said.

"People will think they'll be seen driving into the area with a trailer full of rubbish and come out with an empty trailer."

Mr Fitzgerald admitted it wouldn't work for all comers, especially if only signs were put up.

"To be honest I don't think it would work for some people," he said.

Fees to properly dispose of rubbish at the tip should be lowered, he said, in order to encourage people to properly remove their waste instead of dumping it around the region.

"It costs too much to go out to the tip, it's $50 up to $180 for a firefighter I knew who went out there with a full trailer," he said.

"Dumping rubbish is getting really bad across the whole Central West."
