Antipodes is a term often used for Australia, and antipodean is the adjective/description. In fact, CapriUni is right: it refers to diametrically opposite places, items, etc, but the Brits were being a bit egocentric at the time when they took to calling Oz the Antipodes. In fact Britain is also the antipodes of Oz.Enough of this: on with the show. $US20 would be about $AU40, with the exchange rate the way it is at present, so that would have to be my upper limit.
