Hi Andrew,
indeed a great initiative and yes the NSW import has stalled way too
long.
You will also need to detail how to deal with Unit numbers. For the NSW
import there where many single houses that had several entries like 12A,
12B and 12-2 Lakewook Road. Do you import them as individual nodes? or
just one omitting A/B/2?
My comments, also based on some of my NSW import experience below in
line.
Cheers, Seb

Some specific topics for discussion/feedback I have so far are:
1. How should we handle existing address interpolation ways? Should
these be left as they are or replaced with individually mapped address
points? I'm proposing we replace.
2. Should we also import `addr:suburb`, `addr:state` and
`addr:postcode` tags? I'm proposing we do.
I vote for adding the information. I have been adding it where possible.
In theory the POI should know in which State or LGA it sits but the
reality is that this does not result in the user having complete
addresses on the POI. E.g. restaurants don't have the suburb
automatically shown in OSMAnd.
I would also argue that the information is part of the full address of
the house/building. Else I dare say we should have a similar discussion
for phone numbers. We don't need to add +61 or (0)2 as this is implicit
by the POI location.
Given postcode regions aren't mapped, then adding these to the address
should be very helpful.
`addr:state` is less important given these addresses fall within the
Victoria state admin boundary already. The wiki touches on this saying
"A few mappers consider higher-level tags, or even addr:city=* as
redundant, since they could be calculated from the respective boundary
relations they are contained in (if present and valid). However, such
practice has severe disadvantages and can lead to wrong results."
Either way, I don't think it matters too much, but since it's not
harmful to include, and might provide some benefit, then we may as
well include `addr:state`?
State and post code are part of the full address. I vote for including
it.
`addr:suburb` is similar to `addr:state`, suburb/locality boundaries
are already well mapped in Victoria. Since we have this detail from
the source data I think we probably should still include it.
3. `addr:suburb` vs `addr:city`.
Both tags are in use within Australia. According to taginfo
(https://taginfo.geofabrik.de/australia-oceania/australia/search?q=addr%3A)
within Australia addr:suburb occurs 521 ,671 times and addr:city
562,542 times.
The iD address preset fields uses addr:suburb.
Victoria only has a handful of place=city objects
(https://overpass-turbo.eu/s/17vc), Melbourne, Geelong, Ballarat,
Bendigo, Shepparton, Warrnambool, Traralgon, Bairnsdale, Wangaratta,
Wodonga, Horsham, Mildura.
Because for addressing, it's the suburb/locality that appears on the
address not the city (eg. Melbourne place/city covers the whole
greater melbourne urban area, but not all the addresses here include
"Melbourne", only those within the CBD area where the Melbourne
place=suburb exists.
While in rural areas it's a locality not a suburb, the two usually go
hand in hand, and I'd say it's okay to still tag these as addr:suburb
even though it's technically a locality and not a suburb.
In this way I'd argue that addr:city has no place in Australia
(convince me otherwise).
Not sure if I want to convince you.
To me this sounds like different names for the same thing. Aren't City
or Suburb just different words for the next level up from Street?
The Auspost is referring to 'placename/suburb/locality' page 25
https://auspost.com.au/content/dam/auspost_corp/media/documents/australia-post-addressing-standards-1999.pdf
For the NSW import I recall that I settled for city=<name that
corresponds to a post code>.
Maybe for this import, where we find an address existing in OSM and it
has addr:city which matches the addr:suburb from our Vicmap address,
then we automatically swap it to addr:suburb?
