Let me know if this works for you: http://www.inaturalist.org/places/inaturalist-places.csv.zip
Some of the columns need some explaining, so maybe this needs a metadata file in the zip, but for now it should provide you with a list of iNat place IDs. You can use the slug column to link to the place page on iNat, e.g. https://www.inaturalist.org/places/lonsdale-camp-bush
