I found https://www.openstreetmap.org/node/12419076028 as one feature imported with addr:flats10. Could we move this discussion to the community forum or a GitLab issue at https://gitlab.com/alantgeo/vicmap2osm/-/blob/master/README.md or the import page talk, https://wiki.openstreetmap.org/wiki/Talk:Import/Catalogue/Vicmap_Address
