Broken Hill (Line of Lode)
The mining city in far western New South Wales built on the Line of Lode, one of the world's largest zinc-lead-silver orebodies, formed about 1,690 million years ago; its discovery in 1883 gave rise to BHP, and in 2015 it became the first Australian city on the National Heritage List.
