  :::Just to throw a spanner in the works, Lake Macquarie was proclaimed a city in 1984, well before 1993. Lake Macquarie isn't in the GNB list because there's no actual place, other than the lake itself, that is called Lake Macquarie and it's a bit hard to call a body of water a city. If you limit the list to the places in the GNB register you'd have to exclude Coffs Harbour , Gosford , Griffith , Lismore , Maitland  and Nowra . Lismore and Maitland are tricky ones though. Despite their designations as a locality and a suburb respectively, their descriptions call them cities. Unfortunately I don't think we can restrict the definition that way. I really think we have to stick with official designators in order to avoid breaching WP:OR unless we want to cite WP:IGNORE.
