In regard to ABS data ... I understand that it was added
into OSM when it was the only data for which we could get
permission. ABS statistical areas approximate suburb
boundaries (perhaps 90% similarity). In the Sydney suburb
where I live, the ABS boundary is almost exactly the suburb
boundary that existed more than 20 years ago (last century!)
but the official boundary has now changed. Now that we have
accurate data on suburbs/localities, I think we should
remove references to ABS data.<br>
<br>
In regard to mapping localities ... I don't have knowledge
of the Gold Coast but, in NSW, I see localities as
non-specific areas without precise boundaries and which are
are smaller places within the bounded places usually
referred to as suburbs. If there are official boundaries
for Gold Coast localities, then I withdraw my comments.
However generally I think the suburbs are best mapped as
areas with precise boundaries while localities are mapped as
nodes. In rural areas, these places are often unpopulated
and mapped as "place=locality" or one or two houses mapped
as "place=isolated_dwelling" (both of which I have used).
In metropolitan areas, they can be mapped with a node
"place=neighbourhood" (which I have used) or "place=quarter"
(which I have not used).<br>

<div>For place=* yes best to use local knowledge, but for the
actual administrative regions (which is what's being
proposed for import here) as boundary=administrative, there
are no gaps, so anywhere on the country has a
suburb/locality administrative regions.</div>

</div>
<div>It makes sense to co-mingle the place=* and
boundary=administrative where they are the same, especially
for suburban suburbs, but in rural areas if the imported
region doesn't matchup with the place name, then you can
separate out the boundary=administrative from the place=*.</div>

<p>I'm not clear on what would be used for Level 10 if
Suburb/Locality is moved to Level 9. However if there is a
sensible use even in one or two sates/territories then I think AU
wide we should shift to Level9.</p>
<p>Would it make sense to add existing and suggested authoritative
source for each level to the spreadsheet? Thanks for the ABS
background!</p>
<p>Cheers,</p>
