The most recent occupants (and visitors) tend to be only mobile in motor-cars. "Most people try to traverse the [Nullarbor] journey as quick as possible and they just endure it..” Maybe this is not a remark about the Nullarbor, but about a way of perceiving the environment (in Australia) when racing to get to 'it' or 'getting away from it all'. Knowledge and a positive disposition to the land (scape) would probably aid 'seeing'/understanding.The inability to see 'country', makes Australians pop BIG artifacts into the landscape, usually after it has been shaved. Then there is a reason to travel to 'it' and pay for 'it'.
Already impacts by increasing visitor numbers is resulting in damage. The N.P. is the size of Tasmania and enforcement is limited by staffing. Golfing is associated with huge water needs and mostly toxic run offs. This would impact significantly on the diverse marine and terrestial flora and faunaof the area.
Could the Federal Government not fund its unique natural assets, instead of furthering another unsustainable venue, that might eliminate what is special about Australia. Local or o.s. tourists are unlikely to visit such a venue. Keep the natural, indigenous, paleontological heritage of the Nullarbor plain as an asset.
