Correct.

And I'm simply upholding the OpenStreetMap community policy.

Parks Victoria can do more if they want to work with OpenStreetMap, and I hope they do. While it's great they publish content under CC BY 4.0, like other Victorian departments https://wiki.openstreetmap.org/wiki/Australian_Data_Sources#Victoria they could complete a waiver so it's clear we can use content they publish to improve OSM.

For example https://www.parks.vic.gov.au/-/media/project/pv/main/parks/publication-uploads/dandenong-ranges-national-park---map---ferntree-gully-area_08032023234117695.pdf?rev=77059838aa194edaa1d3f3136cbdfaab is CC BY but not available for OSM to use due to this.

Along with this and a more pro-active collaboration with OpenStreetMap around the current situation on the ground would be helpful.
