I deleted your coarse landuse boundary as it already mapped correctly.

Hi, the Calderwood boundary is already mapped in osm.

Hi, there has been recent discussion about changing roadway classifications on our community forum.
https://community.openstreetmap.org/t/recent-road-hierarchy-retagging-nsw-sydney/131206/4

Hi, Sadleir Street is the correct spelling. I have corrected it.

Also added a few driveways to clarify property access.

A building tag is only used to outline a building shape. The land is already tagged as landuse=residential but a polygon encompassing a larger area as well as landuse=greenfield for this block of land.
If you want it to be displayed differently you could map a surrounding fence line if it is present.

Reverted duplicate parking and deletion of road section. Road name is correct.

…also I noticed other maps have this road named Millbank (with two ll’s) as in the nearby Millbank Reservoir. Can you confirm the correct spelling too, thanks?

Hi, I noticed you have deleted the end of Milbank Avenue. Was this intended?

I have reverted this changeset that has not provided a correct physical location for their business.

Hi, your comment is 'culvert' but you tagged as waterway=milestone.
As a milestone seems unlikely, did you mean to draw a small section of the waterway below the road here, perhaps joining Tallebudgera Creek, and tag the section under the road as a culvert with...
waterway=stream
layer=-1
tunnel=culvert

I have reverted all your changests in
changeset/167050778

Hi, you are editing a public map not your own private map. All the edits to road class classification, etc in all your changesets are incorrect.
Please read the guidelines on our wiki in relation to the highway classes as used in the osm.

Hi, I have reverted this changeset which incorrectly turned a one-way part of a divided main road to two-way and shifted cycle lane to wrong side on this section.

Thanks Eatham

Apologies, it is visible on Esri imagery. I’ll fix soon by reverting part of the changeset.

Hi, you need to place the business at the office you operate from instead of out in a vacant paddock. Also include the addr:housenumber on Forestdale Road.

no response, deleted attraction

The old site building has been razed and roads constructed on old site so mapped roads and left address off.
I entered the new NAA site details and fixed shifted node.
Cheers...Keep on mapping

Hi, you could have left the address info at the old address and just deleted the NAA details.
Have you entered a node with NAA details at the new address?
You have accidentally shifted a highway=crossing node.

I can fix this if you prefer.
