Australian would have been counterproductive, as there was a time when it could be said Australia uses -ise; Britain prefers -ize and America use -ize. Nowadays I have no idea if there'r any distiction - maybe just permitting one to spell “program” correctly? Before computer dictionaries one Australian newspaper used “color, -ise” as its spelling which I find preferable.
