No worries, mate.

This is the ubiquotous greeting in OZ.

The post below mentions our stay at a B+B in Alice run by an ex-pat from South Africa and wife. He was telling us that he sang in the local glee club and was just off to choir practice. First we had tea and honemade cakes with them. During tea he wandered next door and on his return I asked if he kept a bird as I wondered where that "tuneless whistling " was coming from. He kept no bird and later I saw him making those tuneless whistles himself. He did not look pleased. Foot in mouth disease again.
