4 years ago I've bumped into the same issue with Doncaster in Victoria. After doing some research into the cause this is what I'm finding - this is more for @jgc234 as repo owner.
- osmnx.gdf_from_place() is used - osmnx uses the Nominatim API to process this request which is returning a Node for some suburbs, without boundary information attached as far as I can tell.
- osmnx can use overpass requests - osmnx.downloader.overpass_request() might be better suited for searching for postcode level boundaries of suburbs.
- You can play around with the overpass api here: https://overpass-turbo.eu/
- A helpful query I've found for identifying boundaries within the bounding box has been: [out:json];(relation[type=boundary][name=Doncaster]({{bbox}}););out body;>;out skel qt;
- Doesn't seem like there's an easy solution to this problem - and OSM being open, I bumped into different relations / boundaries / etc in how they were entered in OSM.
One possibility could be to provide instructions on identifying the boundary ID, then use that as an input in the script. Reuse the code from osmnx.gdf_from_place() to ingest a overpass api json response instead. I'd be interested in helping out if that would be helpful and a worthwhile direction to go @jgc234?

Hi Jim,
Awesome! Thanks a lot for releasing. This is my first foray into Python/coding and i have managed to figure out enough to get things setup. I am playing around with Perth suburbs. But having some issues. It seems there are no suburb boundaries saved and just nodes for the centre of the suburb. Example: https://www.openstreetmap.org/node/31071659#map=14/-31.9799/115.8057
If i search for "City of Nedlands Western Australia Australia" then i get the council boundaries. https://www.openstreetmap.org/relation/11343563 GPX route attached; City of Nedlands Burbing.zip Only 275km to try and do in a day. ;)
But a lot of the councils don't have their "City of __" boundaries listed on OpenStreetMaps. So i guess i need to learn how to use shape files now?
Also, any idea how to get it to work for USA? Or would the code work if there is a way to make a custom shape file for an area?
Look forward to your responses. And keen to learn more from here.
Thanks
