Git also spelled "Ghet" (perhaps to accommodate publishers' use of English and censorship) in some North Country writings -- I think the term is used profusely in "Kes" by Barry Golding and in "Billy Liar."
The Aussies's use of the word "Bastard" is summed up by John Clement's rather witty, pre-Australian National Anthem, skit: "For a country that doesn't have a national anthem, it does have a national adjective ... friends will use it to greet each other with phrases such as 'How are you goin', you old bastard, what'll it be?,' ... If a stranger uses the word Bastard, he will need reinforcements ... the best kind of bastard is your friend, but 'That Bastard ...' is indeed a real bastard ... and 'useless, bludgeoned bastard' has no friends at all, but fortunately, is extremely rare ... use the word as much as you like ... just don't say it to anyone ..."

Cheers,
Happy Australia Day!
