Hi, I have reverted your addition of a building over a large residential area.
Please only add things that exist in the teal world to openstreetmap.org and especially don’t damage the map for gaming.

I think the buildings are just well hidden amongst the tree foliage. I have corrected the addr:street tags.

Hi, the addr:street tag is for the physical location which is Mitti Street for all three buildings. Have you plotted the building unit footprints here? There appears to be no building at each location on satellite imagery.

Hi, you are meant to accurately outline the house shape instead of placing a rectangle on each property.
You need to reshape each one.

Who is checking the quality of these mappers?
Three buildings in a row have incorrect angular indents at the front.

Qld coast repairs now complete.

Hi, I have begun repairing the osmi areas along the Qld coast following the beach revert.

Hi again, not sure if these problems were from your editing as there have been a vast number of reverts around the coastline to beaches due to a unsuitable source used.
I haven’t had a look what the osmi errors involve either.
This changeset comment may be related to the osmi errors…

Hi
There seems to be a problem to fix here
https://tools.geofabrik.de/osmi/?view=areas&lon=143.90554&lat=-13.50026&zoom=8

Regarding Yabung
...another curiosity is this section which also carries the Yabung name
way/1110690514#map=18/-37.81434/145.40071 and a small section that it joins way/80398218
The highway tag has been removed so it may no longer be used.

I expect the Magpie Trail relation is ok. It seems to have 3 options to join or exit it at the northern end.

Is the Magpie Trail relation correct?
relation/2948297#map=14/-37.8179/145.4002
It appears to be made of two crossing trails.

I'm also accepting of the Lily and Maizie Islands one member MPs. Reusing the same way in MPs to have one feature per mp.

You should draw the outlines of the buildings along the driveway and add address tags to those instead. See other examples in the area that have address tags added.

Hi, the private driveway off Centennial Crescent should not have a name.

This is all fixed now.
I don't see why Lily and Maizie Islands need to be single member multipolygons.

Hi
I corrected the phone and opening hours format.
osm.wiki/Australian_Tagging_Guidelines/Australian_features#Phone_Numbers
opening_hours=*#Syntax
Your Sunday format can be off or closed whichever preferred.

There are sections on this osm wiki that give examples of valid and invalid multipolygons
osm.wiki/Relation:multipolygon

…could it be that the hospital was correctly mapped before this. In that case it might be easiest to revert your change.

Hi
Osmi informs that the multipolgon needs correcting
https://tools.geofabrik.de/osmi/?view=areas&lon=149.15488&lat=-21.14709&zoom=17
I haven’t looked closely at this but expect that polygons with outer role are touching and this makes the multipolygon invalid.
You should use the osm wiki to understand what makes multipolygons invalid.
You should use building:part method instead of a multipolygon, but the individual parts don’t render on the map yet, so you may prefer to map each section as simple polygons instead.
