The vast cattle and sheep industries, the strange aspects of the country, and the strange native animals, brute and human, are matters which would naturally breed a local slang.

I have notes of this slang somewhere, but at the moment I can call to mind only a few of the words and phrases.
They are expressive ones.

The wide, sterile, unpeopled deserts have created eloquent phrases like "No Man's Land" and the "Never-never Country." Also this felicitous form: "She lives in the Never-never Country"-- that is, she is an old maid.

And this one is not without merit: "heifer-paddock"-- young ladies' seminary.

"Bail up" and "stick up" equivalent of our highwayman-term to "hold up" a stage-coach or a train.
