Holsworthy was one of the locations that was looked in the '90's.The Army resisted ferociously any intrusion on their playground.One of the arguments they threw up was that the entire area was virtually an Aboriginal Sacred Site,something that obviously hadn't concerned them for the 60 odd years that they'd been bombing the crap out of the Sacred Sites with exploding ordnance and ordnance which didn't manage to go bang. German cities,after WW11,were littered with unexploded ordnance most of which was a lot larger than anything ever seen at Holsworthy yet somehow those crafty Germans managed to clear the cities and carry on building.
