If we're 'going international' though, how should we say "Merry Christmas" to our Ozzie friends here? Perhaps "Don't put Santa's reindeer on the barbie, and may your tinnies always be cold, cobber" might suffice?
Frohliche Weinachten! (Haven't got an umlaut on my keyboard)
To any of our German friends looking in - hope I've spelt it correctly. My German is a bit rusty these days...
