Yes, agreed. At a quick look, the quality seems to be better in some areas than others, some of the suburban areas of Perth come out pretty well. Anyway, if it's useful to anyone, I now have a folder of ~1700 .osm files for all the suburbs in Perth, happy to share them if anyone wants. I'll probably do some tinkering with them, as a JOSM learning exercise.

Cheers

    That was  also my plan John.  The Kings Park data set looks like a
    perfect example.  I can load that as a layer and compare the
    existing OSM data in another layer.   It is not that difficult to
    select a number of building traces at a time and bring them in. 
    However the Kings Park data is already showing some
    inconsistencies.  For Example Fraser's Restaurant, circular
    building is showing as orthogonal.  Many of the other buildings
    are also incorrect.
    Oh well perhaps it is just another tool that can sometimes be useful.
    Good effort anyway

    Seems sensible to me, I'd personally be shying away from imports
    without more knowledge of how that works. I was thinking about
    biting off very small chunks (even suburbs may be too big for
    this) and manually going over them, making sure to not overwrite
    existing buildings, and checking them individually to make sure
    they match up with relevant imagery. Is there a recommended
    workflow for this?

        Just to flag a note of caution here - I'd recommend small

        test imports; in a sandbox environment.

        If there is interest; later we can create a bunch of tasking
        manager jobs for importing small chunks at a time; plus write
        up the plan(s) as needed

            Hi Warren, I've split it out into .osm files for each of
            the WA suburbs [1], see attached small example file for
            King's Park. Does something like this work? I can drag
            and drop them into JOSM, but I'm not 100% sure if they're
            formatted or attributed correctly to be most useful.

                Hi John
                I use  JOSM.  Any file format that I can bring in as
                a layer would be fine.   I can then select, copy and
                paste the tracings into an active layer for upload,
                checking  as I go.  Certainly faster than tracing by
                hand.
                I am not sure when JOSM get chocked by file size, but
                say Perth or the South West of WA may be enough of a
                reduction.
                Thanks

                Hi Warren, I could probably help with this. What
                would be a good size for a chunk? What would be a
                useful format?

                    Hi

                    I am in the eastern suburbs of Perth where
                    minimal buildings have been
                    traced.  I would be happy to check trace data in
                    my area, lets face it
                    hand tracing is not much fun  and very time
                    consuming.  I think some
                    inaccuracies are acceptable, they can be
                    modified as they become apparent.
                    The data at
                    https://github.com/microsoft/AustraliaBuildingFootprints
                    <https://github.com/microsoft/AustraliaBuildingFootprints>
                    is
                    much too large for me to handle.
                    Is  someone more skillful than me able to break
                    this data set into bite
                    sized chunks?
