Have you decided how you are going to fix all these buildings?

I have reverted this changeset of duplicated mapping

These sites are already mapped.

Hi, welcome to osm. You have been adding invalid multipolygons.
https://tools.geofabrik.de/osmi/?view=areas&lon=152.34933&lat=-24.86866&zoom=14
There are examples of invalid types here
osm.wiki/Relation:multipolygon
You should use building:part relation kind instead or else use delete all the multipolygons and use simple polygons to draw each section.

Please zoom in very close on all the junctions to see if they meet and are joined correctly.

Hi, you need to check the junctions where ways meet. If you zoom in very close you can see some do not join or meet correctly.

sport=free_flying
leisure=pitch can be added to a node or circle if bounds of the area are not known

Hi, welcome to osm.
Consider adding leisure=pitch to all these instead of the shop.

I deleted waterway=stream from section of admin boundary for Balmoral Ridge and North Maleny in changeset/152518932

Looks like you may have deleted some of the admin boundaries

Hi, osmi finds an error in the area boundaries here

Hi, welcome to the osm.
You are expected to outline the building instead of the plot of land when adding a house.

Street names should not be abbreviated in osm

Ducklo School Road on each side of this section you have renamed Ducklo Gulgera Road.
Would you be able to survey what all sections of the road should be named?

I have fixed these

Hi, this appears to be incorrectly placed. 5A Edward St is further south along this road.
