I could find a decent number of attestations of australsk to mean Australian English and britisk to mean British English in major news publications, but I found no attestations for kanadisk, ny/newzealandsk, or sørafrikansk to refer to Canadian, New Zealand, and South African English respectively. So it seems to be very case-by-case, maybe related to the prominence of Quebecois French, Maori, and Afrikaans in those countries? And irsk already refers to the Irish language, so that doesn’t work; indisk refers to any language of India but English; and I don’t think I’ll get any relevant results for anything else.
In my own experience, amerikansk in the sense of American English is far more common than australsk and britisk in the senses of those varieties of English. Indeed, amerikansk is the only one of these three words where “variety of English” is listed in NAOB as a sense. "Snakker britisk" -engelsk -reddit got 616 Google results; "Snakker australsk" -engelsk -reddit got 62 results; and "snakker amerikansk" -engelsk -reddit got 1,030 results, for whatever that’s worth.
Interesting, does that hold for other dialects or regional variants of English or other languages?
