In extreme solar max's, aurora australis has be seen as far north as Singapore! thats extremely rare of course, from Adelaide we see plenty at solar max. routinely in fact, as the geographic lat. and long. are not relevant to Aurora, as they are governed by geomagnetic grid, lat. long.
and that is tilted at such an angle at present that Adelaide is at geomagnetic latitude 42 or 38 south? hmmm cant remember off hand, but at 35 south as far as the normal globe is concerned, actually WA is even well favoured.
