You don't need the is_in tags, you use administrative boundaries to find that information out.

Exactly, although to make it easier on apps they can pre-process the boundaries and the stuff in the boundaries to know what a town or way is in, for is_in to actually be useful it would have to be applied consistently to everything, not just boundaries, and that isn't likely to happen nor should it when that information can be extracted from boundaries.

This way if you wanted to find a post code, you can just look for the post code boundary.

This is also why I was suggesting using admin_level=9 for town boundaries, for towns like gympie that don't match postcode or admin_level=10 boundaries. Then that information can be used to find any street within the Gympie town area, not just the ABS Gympie boundary.
