Deary deary me. You lot are insane.
The ACT has several districts, which include the suburban districts of North Canberra, Belconnen, Gungahlin, South Canberra, Tuggeranong, Weston Creek, and Woden Valley. It also has rural districts such as Pierces Creek, Jerrabomberra (not to be confused with Jerrabomberra, NSW), Kowen, etc. Any district north of the Molonglo River is consider to be "northside", and conversely, anything south is "southside".
Places like "Lanyon", "Erindale", etc are localities that aren't official names of suburbs or districts.
For the record, seeing as it's being discussed, I'm 27. I also live in Wanniassa, but in 3 weeks time I'll be moving to Surry Hills.
