Trumpy:
Do Australia use these PDL-plugs too? Are they good? They look sturdy.

(The IEC 309 plugs I've encountered would probably survive a nuclear war...)

Ranger:
That sounds like it could be the same plugs once used here.

These are becoming uncommon since they have a nasty habit of electrocuting people. (They are made of metal) Of a total of seven electrocutions in Sweden last year, two were caused by these plugs.
