You never want an Australian with his back against the wall. You put any 12 blokes together and you'll get a job done. Whether it's getting a bogged four-wheel-drive off the beach or standing in front of a cricket wicket and making sure we're in a dominant position. It's the same dog, different leg action, so to speak.
When a soldier complains of his hard life (or a labourer, etc. ) try giving him nothing to do.
