*suburbs imply its part of a greater city area, I'd expect either town or locality(less correct location) assuming localities would be necessary in circumstances Coondle, Nobel Falls(border line town), Morangup, Moondyne, Nardie etc though Towns like Toodyay, Gidgee, Chidlow maybe needs a second parameter/switch to define them, even a burb option for Toodyay road case where it passes thru all three types.
