I miss Aussie slang, And they don't even have "paint the bowl", "tag and release a brown trout", "flat out like a lizard drinking", or "she looks like someone set her face on fire and tried to put it out with a bike chain". Oh yeah, a warning: the language in that page is a bit on the colourful side.

There's also "up sh*t creek without a paddle" (which is sometimes "in a barbed wire canoe"). I found another page, but it gets pretty nasty at times, despite some good stuff.
