Thanks Andrew, I have looked at all of the tags in the raw data and have created a Python file to process this.
I have considered the ‘Unknown’, ‘Not Applicable’ and also removed the trees where they are ‘stumps’ or ‘vacant’. The data is linked here: https://data.gov.au/dataset/ds-dga-80051ffe-04d5-4602-b15b-60e0d0e3d153/ I have actually proceeded with a test import on a small area in Seabrook. A reason why I think a source tag would be useful is the identification of imported trees in subsequent updates from Council being imported. I note that this test import is easily reversible by me if plans do not eventuate. The test import changeset is here: https://www.openstreetmap.org/changeset/69182499#map=16/-37.8860/144.7627 Also, there is a non-existent boundary through Seabrook Primary School that renders on Mapnik. I noticed this during the test import and am unsure of the issue here.

Do you either have a sample .osm file or could you post an example of what tags/values will be imported? Can you say anything further about how you will transform the data? ie. removing "Unknown" values etc. Regarding the source tag, I think it must be on the changeset, but can optionally be on each object as well. It was once pointed out to me that the source on the object may lead to editors thinking they can't change/touch the object, and it can also be misleading when changes subsequently happen. Mind you, I still add source, source:geometry, source:name etc. tags where I feel it's appropriate manually, I just don't think it's essential to have them on each object. Feel free to post a link to this thread https://lists.openstreetmap.org/pipermail/talk-au/2019-April/012577.html as a changeset tag or comment to help link the import back to this discussion.

The data has been verified by myself with aerial imagery and DELWP/VicMap boundaries. I will be importing small squares of data at a time, including the tree circumference, species (if known) or genus (if species unknown). Tree circumference in the data are grouped by ranges of 150mm. I have taken the maximum of these ranges to be the circumference in my code. A source tag will be attached to each tree node imported, source=data.gov.au:Hobsons Bay City Council, and also on the relevant changesets. A waiver has been signed by Hobsons Bay and is available on both the Australian Data Catalogue page and the Contributors<https://wiki.openstreetmap.org/wiki/Contributors#Hobsons_Bay_City_Council_data> page. Any questions or feedback regarding the import would be highly appreciated, including whether the approach to the circumference tag, and source tag is acceptable.
