The Chinese also use the American two-pin plug and the European two-pin plug.
Yeah, yeah, I know the Chinese knock-off of the American plug doesn't have holes in the pins and the pins are a millimeter shorter, but that's not a significant difference to affect operation if that same plug were stuck into an American-market socket.
Apparently the Chinese use the two-pin American plug for un-grounded small appliances (like table lamps and clock-radios) and the Aussie-style plug for larger Class 1 devices (computers, washing machine etc.)
I've read that the Australians require their plugs to be ROUND and adhere to a strict set of dimensions, while I've seen the Chinese-market "Oz-Plugs" with octagonal, round, square form factors.
Therefore these won't fit into an Aussie trailing socket (which must be shrouded and recessed) on an extension cord.
