not sure it happens, but with say government stuff (tax, centrelink, whatever), if ‘em’re (offshore call centres) not australian citizens(people operating them) and not located in australian territories, is an australian citizen obliged to grant them any legitimacy and authority (under law) in handling any of their (an australian citizens’) business?
perhaps related, of overseas security/intelligence agencies, activities relating to citizens of australia, for the australian government.
similarly there’re commercial interests that cross the borders of nation-states.
