From Cricinfo: ""Australianism," wrote Arlott, "means single-minded determination to win - to win within the laws but, if necessary, to the last limit within them. It means where the 'impossible' is within the realm of what the human body can do, there are Australians who believe that they can do it - and who have succeeded often enough to make us wonder if anything is impossible to them. It means they have never lost a match - particularly a Test match - until the last run is scored or their last wicket down."
What is it about them? Are they all born with a node on the brain that says "be an annoying ***** and do the impossible" when the going gets tough? Where does it stem from? Can it be bottled?
