Ah, that's very interesting - I didn't think of that. Australian towns
tend to be very far apart, so the boundary of two *towns* rarely meet.
(Other administrative boundaries, "shires", do...)

Cool. So preferred tagging is:
1) Node in centre of town with place=town
2) One or more boundary ways with boundary=administrative, admin_level=8
3) Relation linking the two.
