Hi
ARTWALK = SHAC2022 is not a recognised tag and does not belong in the OSM. Perhaps you could use the ref tag for this or the description tag.
Name is for the name only...also not all in uppercase...
osm.wiki/Names
Many of your names I have changed to description , including name = Private House.
Some names end in "in 2022" which I deleted as it is not part of it's name.
Other tags you are using don't seem to exist yet.
Don't be discouraged or annoyed at these changes.
The OSM is essentially a database with tags and mapping topology confined to a consensus method of mapping.
With these rules, maps are able to be rendered correctly in an expected and consistent way.

I have changed some of your tags and have remapped the outline of some of the buildings. I have also added a primary tag to identify its use such as ...
amenity=pub
amenity=cafe
office=company
amenity=clinic for the podiatrist
etc

no response, reverted changeset/118523921 and 118545869 as both mapped to wrong location as tagged and I am unable to map to correct location using permitted datasets.

I used a few multipolygons at north part of PC hosp to take grass areas of buildings. Hope you don't mind.

I linked the end of these footways to the one across the road. Footways are not limited to having concrete surfaces.
The links are needed so that pedestrian routing can work properly.

Hi
I was trying to some park problems here but the JOSM validator picks up this error ...
Overlapping Identical Landuses]
Hazelcroft Estate and
Riverstone At Plenty River Estate

Are you able to fix it?
Let me know if unable, thanks.

Hi
I changed this to a multipolygon so that the island can render

works for bikes too
osm.org/directions?engine=fossgis_osrm_bike&route=-33.62184%2C151.14947%3B-33.62168%2C151.14858#map=20/-33.62175/151.14903&layers=Y

This router is working fine at crossing the road.

There is no need to try unusual tagging for Alltrails.
Alltrails may update the maps more regularly than the routing part of their database which may take weeks or months to update.

Hi
I am curious why housenumbers 4 & 5 were deleted as there appear to belong to the adjacent houses.

I changed this to a simple polygon

Hi
I shifted your edit on to the listed address as it was plonked on the wrong building.

This business seems to be placed at the wrong part of the map.
50 St Georges Terrace is not at the site of the Saint Andrews Church where you have placed it.

Most seem to be not part of the public road network too and if on private land, access=private could be added.

Hi
these seem to be mainly driveways to individual houses and would be better tagged as highway=service + service=driveway
The wiki seems in need of improvement in regard to this.
highway=service

Product advertising such as your video product spam is not permitted

The shopping centre is a simple outline and there is no need for a relation.
Why don’t you join the two section and delete the relation.
I expect it is the iD editor that does this type of stupid creation of relations.

Hi
I changed the boundary name to include these tags...
amenity=social_facility
landuse=residential
name=Araluen Centre
operator=Araluen
social_facility=assisted_living

Please fix if incorrect as I am remote from the area.

Hi
I think natural=grassland is incorrect tagging for areas of the asphalted car parks in PC Hosp. You could micro-map the tree and garden areas finely where they occur instead if you wish.
