I saw this in one of the papers too and thought how different you in Australia. The bird would be assumed to be an aviary escapee, a potentially invasive secies (parthenogenic hatchings aren't out of the question - just rare) and I'm pretty sure that if it turned up in Tassie or WA it would be shot on sight by the authorities.
Recently (last month) a first for Australia turned up in a backyard near Cairns, Much the same thing happened, just no entry fee, and there was alot of etiquette towards the bird (Ie, no one stressing it out for a picture or something)
