A better view of the OSM Inspector area of concern
http://tools.geofabrik.de/osmi/?view=areas&lon=152.96835&lat=-27.15172&zoom=18

Also iD editor is rather limited in making relations, use the JOSM editor instead.

Hi
I noticed that the OSM Inspector site finds duplicated segments in your relations
http://tools.geofabrik.de/osmi/?view=areas&lon=151.27881&lat=-26.95733&zoom=8
I suggest using Esri imagery for better clarity (and possibly more recent too) and you will find there is a gap between two kindergarten polygons.
Polygons cannot share outer ways, so for the two kindergarten areas, it may be best to just make a single polygon surrounding all the kindergarten boundary as amenity=kindergarten
amenity=kindergarten
Then make the buildings in the kindergarten part separate and tagged as building=kindergarten or building=yes and the grassed play area as landuse=grass or maybe leisure=playground and access=private.
building=kindergarten

Regarding Mazenod, you will find the Esri imagery better. Again two outer ways in multipolygons cannot share borders.
So you may find it easiest just to have one polygon around the whole building or you could also still mark different parts of a building using 'building parts'
building:part=*

Rodrigo Hall is similar problem

A bit of general info on relations
osm.wiki/Relation
osm.wiki/Relation:multipolygon

If two separately grouped multipolygons share a segment along part of their boundaries, you need to split the ways at each end of the shared bit, delete one of the segments and then share the remaining one in each multipolygon otherwise you will see OSMI Inpector show a 'duplicate segment' problem.
The ones you mapped are not like this.
These commonly crop up where for example, a National Park multipolygon shares part of a boundary with a State Forest.

Cheers, Nev

no response, fixed it myself

Hi
Welcome to osm. I reverted this change as you dragged a point connected to the park to the roadway. Please try again by just extending the path.

Hi
I edited your business tags as I expect the shop tag value was not generic enough to render on the map. I added the previous shop value to a cuisine= tag.
Please check in a couple of days to see if it renders on on the map.

Adding a name and all other info in a description tag is not suitable.
Please use something like https://osmybiz.osm.ch/#/9/-27.49122/152.67700 or https://www.onosm.org/# to initially help adding your business in to the OSM with suitable tags.

I reverted your business edit masquerading as amenity=place_of_worship

Hi
finally got around to redrawing the wooded areas in the vicinity of Buyu and Buluba Nature Refuges. Feel free to amend and correct as needed.

I also fixed the format of the phone and hours tags
osm.wiki/Australian_Tagging_Guidelines#Phone_Numbers
opening_hours=*#Examples

Hi
please place your business listing over the premise you operate from and preferable add the addr tags.
addr=*
I shifted your edit from the roadway to the nearest building. Please correct the placement if necessary.

Ok, thanks NathaniellR

Hi
removing an airport seems to be a big editing decision. Can you elaborate on what developments have resulted in the demise of the airport.

reverted due to po box only listing

I reverted this business addition due to deficient tagging method.

Why have you added amenity=place_of_worship to you business edit?

Hi
If road construction is complete you also need to delete the tag construction=residential

I reverted you business edit due to spam in changeset comment, deficient method tagging, incorrect re-naming of street to business name. This is another of long series of edits of this type of business edit that shows no suitable method for inclusion in in osm and no response to changeset comments.

No response, I deleted amenity = place_of_worship
