This is a list of difference between a list of Sydney suburbs using the definition I suggested at Talk:List of Sydney suburbs and the list currently at List of Sydney suburbs. If a name is bolded, it is a name classified as a suburb by the Geo. Names Board inside the boundary I defined that isn't currently on the list. Otherwise, the name is on the list, but doesn't fit my definition for the reason given. ??? signifies that the name does not appear at all in the Geographical Names Register. Many of the bold names are probably near the boundary - the LGA is given in brackets.
