A call for the Government to tighten up on rules on free-range defecation.

The Responsible Camping Association wants changes to a law that allows people to poo in public if they think they're not being watched.

Spokesperson Bob Osborne told Heather du Plessis-Allan it's a defence to avoid being prosecuted for defecating in public.

“Actually, people seeing others actually doing that is not the problem. The problem is the visual aftermath of it.”

The association wants to ensure waste is buried properly and at least 50 metres from the nearest waterway.
