Victoria is the only state that has boundary=political mapped and all those are state boundaries and tagged political_division = au_vic_la.
NT has Casuarina mapped and that appears in error along with the Kooyong boundary (political_division
  	au_cth_HoR).
I think it should be deleted if we don't have permission to use the source in osm.
The AEC redraws the boundaries before elections and it is probably better for them to provide mapping unless we get permission and have a regular import to keep them up to date.
