South Australia's timezone is already weird, being somewhere between Ballarat and Melbourne iirc (in the winter). It was the first timezone set outside of the territory it contains. The 45 minute offset is just to find the midpoint between the timezone on their east and the timezone on their west.
As for the statement in the article "A couple hundred people can probably come to consensus on just about anything, apparently even the complete departure from a standard time that the government say should apply to them. That doesn’t concern them. They set their clocks as they please. It’s such a small population that the authorities turn a blind eye and allows ACWST to continue albeit without official sanction."
It should be balanced by the image of a sign announcing the timezone, installed by the government. It's probably more accurate to say that they have the tolerance, at least, of the government, but not the sanction of state parliament.
