I see the Aussie common plug and similarity to other countries. The picture shows partly insulated prongs which is a great safety feature I’ve never seen before
Simple US plugs are also not (usually) reversible. Historically they weren’t but the standard changed decades (half a century?) ago to support polarized plugs with one blade wider than the other. If it matters, such as a light switch, the plug must be polarized and can only fit in one direction. For some things, like a sealed power supply it doesn’t matter
There’s always ancient outlets and ancient plugs that never got replaced but those are getting rare
Interesting rabbit hole to drill down into ……

I don’t know whether it’s physically the same size but that’s 240v and US had similar variations at that voltage
