Wikidata and OpenStreetMap/Nominatim gazetteer lookups · Wikidata / OpenStreetMap
Parent place Dundas, New South Wales, Australia (#9590) is geocoded via Nominatim to -33.802949/151.0440587.
No distinct 'South Ryde'/'Ryde South' gazetteer entity was found (search_places for both spellings returns nothing beyond this row; Nominatim returns only unrelated Ryde-CBD points), so the parent district's own centroid is used, matching the convention already used on the sibling 'Sleepy Creek, via Roma' row.
