If you prefer I can try to fix if you put the area back.

Hi, a few problems here due to invalid multipolygon structure.
https://tools.geofabrik.de/osmi/?view=areas&lon=153.41312&lat=-27.27945&zoom=16
Josm validator detects these but it
probably easiest to read the wiki and check the invalid types.
osm.wiki/Relation:multipolygon

Hi, I have reverted this. You need to map your business to the physical address you operate from instead of the edge of a park.

I have fixed this now

Hi, you have joined some paths to the powerline in many places. You should zoom in much further as paths should not connect to powerlines.

Hi, these are incorrect tags for a gate on land.
seamark:type=gate
waterway=lock_gate
Here is the wiki for the gate you want...
barrier=gate

Fixed in changeset/176379076

I have reverted this changeset as I am unable to verify the physical address.

Hi. You have located this business in a position that is not in the vicinity of the listed address on the web.

Hi, you have placed your business node at a position that is not near the tagged address.

Hi, you have placed your business on a city building that is quite a distance from the address tags.

These areas may have been used for titanium and zircon mines/quarry and appears to be defined on old AGRI imagery but appears to be no longer active for these activities.

Hi, there is also a cutline tag for powerline clearing if you need it man_made=cutline

I reverted this changeset in changeset/176324819 using osm.wiki/Osm-revert

This tag is not generally necessary as the boundaries of the districts are already mapped.
Pokolbin:
relation/6059206
Cessnock:
relation/6058958#map=13/-32.83349/151.36709
Nulkaba:
relation/6059187#map=14/-32.80956/151.37684

Was looking at old Sentinel imagery, latest shows what looks like bare ground where the house was.
Thanks all.

Ok, thanks

I expect you found the address tag and building did not coincide and replaced the building with the address node.
