Oh, yes, & an "ear bashing" isn't a threat of violence. Just refers to someone who talks incessantly...
& okkers is more Australian slang, a mildly deroatory term for someone who's a bit thick or else who is 'boorish' & can be used affectionately as well as a mild insult. More likely to be heard out the wop-wops than in the cities these days. The traditional beer bellied aussie always with a tinnie in his hand in other words.
