Thank you all
It is a stunning area of the country. The biggest threat would have to be mining, like the most of WA. I once heard that something like 85% of the Darling Range (which runs near Perth) is leased to mining companies in some way or another. Must be the same up north.
From the air you see areas where they've gone through doing a grid survey and there's a grid of tracks buldozed through the landscape.
It sometimes feels like we're selling our souls to China in the form of ore and the returned goods don't quite cut it.
But hey, I realise many people on this forum earn their living from mining.
Roger.
