They are on King William Street (Pirie Street intersection) and North Terrace so far (or at least those are the ones I have seen).
There is a subtle yet crucial difference between the two. The overseas ones tell you how long it will be before you can cross. Ours don't give you that information. Instead they give you a countdown telling you how much time you have left to scurry across the road.
It's like a silent Sergeant Major barking orders at you to get out of the way.
Nice idea. Poorly executed.
