What is this wall socket for?

My unit was built in Australia in the 60's or 70's and has an odd socket on the wall. It has two small round holes, 2-3mm in diameter, spaced approx 3mm apart. It's above my power point and below the telephone socket. Here's a picture of it. Does anyone know what it is used for?
