Many people consider Emu Ridge to be a suburb name, and it is widely used in Canberra, even on some (though not most) official maps. It does not, however, have any official standing as a place name. There are other instances of estate names becoming de facto suburb names in Canberra, such as Gleneagles, in the suburb of Kambah, Harcourt Hill, in the suburb of Nicholls, and Swinger Hill in the suburb of Phillip. These are all discrete estates within larger suburbs, but none of these names have been officially gazetted by the Australian Capital Territory Government. In recent years an application was made to the ACT Government by residents of Swinger Hill to have their estate name officially recognised as a suburb name, but this was rejected. The ACT Government has, however, erected official suburb signs for Swinger Hill, which it has not done for other estates.
Emu Ridge became especially popular as a name because in Belconnen's case "Belconnen" has been used as the name of the entire district, as well as the central suburb in that district. This has also happened in Canberra's newest district Gungahlin, to Belconnen's north. Other urban districts in Canberra have names for their central suburbs - or town centre suburbs - that are different from the district's name: Phillip in Woden Valley, Greenway in Tuggeranong, and Weston in Weston Creek; Civic, or City, is considered the centre of North Canberra (and Canberra as a whole), while no one suburb is readily identifiable as South Canberra's centre, although Manuka - a shopping precinct in the suburbs of Griffith and Forrest, Forrest - may be considered by many to be that district's centre.
"Emu Ridge" as a place name helps some people differentiate this part of the suburb of Belconnen from the rest of the district of Belconnen. It's inherent "Australianness" as a name, and the fact that it is composed of two words, which is rare in Canberra where most suburbs are named with the family name of a prominent Australian, also make it appealing to some.
