You appear to have deleted the connection of Actil Avenue to the eastbound side of Torrens Road. Was this intended?

Thanks for fixing

Hi, multipolygon relations cannot share sides.
These are the ones affected
https://tools.geofabrik.de/osmi/?view=areas&lon=144.83004&lat=-37.86905&zoom=18
You can see examples of how multipolygons are constructed here
osm.wiki/Relation:multipolygon
I suggest just using simple polygons instead of the multipolygons

Hi, the area tag has been replaced by building=house tag

I have adjusted tags and de-spammed the description

Your edit is correct. I deleted the postcode as these are already mapped by their boundaries but I should have checked when it was added before leaving the comment.
This guide provides a lot of useful info
osm.wiki/Australian_Tagging_Guidelines

Hi, there is no need to enter the postcode as the see are all already mapped by there bounds. I have deleted it.

Hi, you have only mapped two nodes instead of a trail. A trail would normally be a line showing the path or track that you have travelled. A gpx trace of it may be uploaded which you then trace along in an osm editor to map the line, then add the right tags to define what you have added and to describe its characteristics.

Hi Dinil, I re-checked and there were two mapped so I deleted one. Also, if you are entering more of these, the phone format for Australia is +61 3 9902 6011 and I have fixed it.

I see quite a few people entering two defibrillators instead of one and have wondered why. I expect they expect to see a defibrillator icon on there map but the the standard map on osm doesn't render them yet so some mappers might think they haven't mapped it properly. Maybe they get a double subsidy for the extra one. Who knows?

Thanks, I’ll check again later.

You have entered two defibrillators in the same place. Are there two of them?

Please note that part of these two buildings do overlay the water.
so I have redrawn them with more accurate DCS NSW imagery

Hi, the wooded areas need more work.

It seems to me that this relation needs to be completed

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.

Your seo spam has been reverted.

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.
osm.wiki/Australian_Tagging_Guidelines/Cycling_and_Foot_Paths#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
People can download the gpx

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.
