"Little India" is no official place name (see Geographic name Board of NSW - https://proposals.gnb.nsw.gov.au/public/geonames/search ). The problem with "Little India" on the map is, that in some configurations of the map it shows up as sole place name, eg. in the WP article "Harris Park, NSW". Harris Park  over all has a population of 5K, therefore the need to unofficially subdivide even more, seems questionable.
