Most of the UK understandings of the phrases mentioned above seem to have transferred to Australia almost unaltered, although I've yet to hear a Second Division, Second Class, Honours degree referred to as anything other than a 2.2 or (among much older people no longer connected to universities) a 2B.

The national broadcaster here (the equivalent of Britain's BBC) is the ABC and shared similar attitudes and came to share the same "Aunty" nomenclature. Some of the prohibitions now seem incomprehensible. One that comes to mind (an applied to commercial broadcasters as well) forbade broadcasting more than 25 consecutive minutes of opera; this lasted until about 1966.

You can 'whip up' hatred reminded me of a more recently-used term in Oz politics. When a politician (elected or self-appointed) makes a comment that is designed to appeal to racists but avoids overt expression of racism (you can be assured it is designed to "'whip up' hatred") it is referred to as "dog whistle politics". It relies on the popular understanding of those sorts of whistles that can be heard by dogs but not by people. When racism is deployed as an argument here it is referred to as "playing the race card".
