I am not surprised that Oz has (had) problems with asymmetric current. A lot of places where and still are fed by Single Wire Earth Return (SWER) circuits, you don't want any DC on them otherwise bang go the earth spikes.

It is worth looking up SWER, a most ingenious system that is remarkably safe, cheap, and upgradeable.
