Campers who left behind toilet seats, excrement in wombat holes and bag loads of rubbish at a "pristine" camping site have raised the ire of South Coast locals.

Sue Nagle Thorssell, who operates Brogo Wilderness Canoes with her partner Dave, cleaned up after the irresponsible campers in the Wadbilliga National Park near Bega.

She supplied several photos of piles of litter, human excrement and broken camp equipment left behind on the shores of the Brogo Dam.

Four large bags were needed to remove all the rubbish, a clean-up job that she said is becoming all too regular.
