Open the gate.. welcome to this dimension..
We do have limited built structure conservation in Australia (compared to say, Europe), so if you can, you really should support the National Trust of S.A (or the affiliate in your state).
e.g. work being carried out at Moonta Heritage area presently (youtube video)
Also in support of that the National Trust working on trails, e.g. "The Silver to Sea" trail, a Broken Hill to Port Pirie 'trail'.
