Hi, the Hastings Hotel has an invalid multipolygon. Outer rings in mp cannot share sides. You can map as two separate buildings or use the building:part method

Hi, the buildings need to be mapped with a little more care to align with the building footprints more closely. You can hit 'Q' with the building selected to square the shape too.

I am not familiar with CyclOSM but it takes you to OSM to edit the map so you would need to be familiar with the way it's done in OSM.
The are Australian guidelines for our route networks.

You are welcome to discuss this with other members of the OSM community at https://community.openstreetmap.org/c/communities/oceania/73
Looks like someone started a discussion about local cycle routes in Dec 2024 so that may be of interest
https://community.openstreetmap.org/t/lcn-tagging-in-australia/123529/2

If these are personal cycle routes and not official it may be better to add to https://www.wikiloc.com/ or similar.
You can add images and a description, etc.
Here is an example of a hike on Wikiloc https://www.wikiloc.com/hiking-trails/mount-glorious-lepidozamia-road-toward-mt-daguilar-17912069

This is not the correct way to draw a route in osm and I will revert. You don't redraw another way over the existing mapped roads.
To create a cycleway route relation you just add the existing road, track, cycleway, footway etc segments that have already been mapped by others along the route to the new cycleway relation you make.
You are likely to need to split the existing ways where the route shifts from a roadway to another way occasionally.
At times you may need to draw a bit of road or track, etc that hasn't been mapped yet if that is part of the route. You may need to draw a small section to transition from a road to another way where there is no formal way that gets no tags but is added to your route because it is a desired way and so there are no gaps in the route.
I don't use iD and expect Josm would be much easier to create routes.
Here is an example of the local bike route and notice that 21 members (or bits of way) make up the relation.

I have reverted your changes so that you can start with a clean slate to add your cycle route.

Hi, there is a specific way to add a cyle route to osm.
Please read the following and amend you route accordingly.
osm.wiki/Cycle_routes

Hi, you appear to have duplicated the waterway.
One is named Arroyo Lerma Santiago and the other Arroyo Rio Lerma Santiago, Arroyo Rio Lerma Santiago is drawn in the wrong direction. Waterways are drawn in the downstream direction they flow.
I was going to map it to the River Río Grande de Santiago but want to know what the correct name is.

Correction...
close north of Birdsville should read close north of Betoota

Hi, the multipolygon is invalid in osm as sides of rings cannot be shared.
osm.wiki/Relation:multipolygon

These road extensions appear not to exist either

Nothing seen on latest Copernicus Browser image either.

Sorry, I see the source tag now.

Hi, some of the roads have a source name tag. If you change the name you need to delete the old source tag or add the source you are using to that tag. You can add the new source to your changeset comment too or instead.
What is your source for the name changes?

You have missed renaming a section of the offramp as part remains as Fitzgeralds Road Offramp.

Is the renaming correct. All residential and businesses still use Old Geelong Road as their address in the part you have renamed.

Is this a proposed road construction?
No changes visible on imagery.

These changes will be reflected on the Qld Globe soon and I guess eventually find their way into national datasets.
