Declared a criminal by the Romans for the sack of Saguntum, Hannibal took his army from Spain over the Alps to Italy. It's the equivalent of raising an army in Geelong to invade Sydney, with the Snowy Mountains being vaguely analogous.I
have no doubt that if Hannibal was leading such an invasion that it would be a success right up to a certain point.
Being unfamiliar with our geography and slang, Hannibal would be half-way through the Snowy Mountains before giving the order "Sack Crackenback!"
And that wouldn't turn out at all like he was expecting.
