I don't think I have ever freecamped in Nerrandera itself but have either side. If you want south of Nerrandera there is Bundure, a roadside free camp about 70 ks south of Nerrandera and 37 ks north of Jerilderie. You do get a few trucks in over night but there is room for everyone. North of Nerrandera is the pub at Mirool, about 70 ks north, turn in at the large silos, Grand looking old pub, great meals. Freecamping alongside where there are new free showers and toilets. That would be my choice. Large paddocked area to park.
