That isn't an Aus/NZ socket, reason I say that is the the contacts are too far apart for the Phase and Neutral pins of a standard plug here.
It might be an Argentinian version where the phase and neutral are transposed, but don't fit our plugs.
One other thing, anything made for the Aus/NZ market has a switch on it, so you can turn off the 230V before you pull the plug out of the socket.
