Australia has used worded pedestrian signal in the past. Some survive, but their days are numbered.
Here's an Eagle text ped signal in Melbourne, Victoria. The photo was taken last year, but the whole intersection was recently "upgraded" with LED signals on new poles. I've not seen the upgrade, but know a signal maintainer who keeps tabs on these things.

Similar to US ped signals other than the word WALK being in green.
Also we had neon ped signals, although the few survivors have all been replaced recently - with one exception - and that's due to go soon.

This neon in Melbourne is believed to be the sole survivor still on the street. A contract to upgrade the intersection went out recently, so it won't be there much longer.

And here's one of the same types of neon ped lantern (by Eagle Signals of Australia) showing the green WALK aspect.
