Hi, for the business premises, I made separate building footprint and land boundary tags.

I reinstated the landuse=residential area and adjusted out a commercial building.
The building tag is only for building footprints and not for the whole block areas containing houses.

Undeleted Our Lady Help of Christians Primary School

Hi
you could be use a more specific tag for the buildings you are adding.
e.g. building=house
building=*

I think this addition of a park here is mistaken. It looks more like a private driveway and residential houses.
Yarra Glen boundary and a label on Bell Street near the shopping centre is already mapped.
relation/2423695

I altered the mapping here to be consistent with the OSM norms

Hi
It is best to map school grounds to the fence line instead of the roadway centre lines. Accuracy is preferred over aesthetics.

Hi
the new roads you have added seem fictitious to me.
Could you explain your intent and give more information about the new ways you have added, thanks.

Hi
building=house negates the need for
description=House

Also...
I see you have deleted the tunnel from Flat Rock Creek between Strathallen Avenue and where it joins the bay. Does this section still flow above ground across the sports fields.
Difficult see from imagery, but the DCS NSW Base Map has the creek going through the wooded areas to the south of the sports fields.

Hi
the name tag is not used as an address label.
osm.wiki/Names#Name_is_the_name_only
The addr:housenumber and addr:steet already has that information.

Hi
please do not CAPITALISE names... use mixed case instead.
Several good practices listed here...

Hi
please do not use abbreviations in names... I have fixed.
