Reverted.

This;
broke at least 3 administration boundaries,
has no stated source.

Suggest you state the source for all your changesets.

Hi,

You have buildings within buildings.. that is an error. Possibly one of the 'buildings' is a building:part=*?

I have 'fixed' duplicated nodes using JOSM Validator tools - automatic.

Hi,
Welcome to OSM!

The beach you added has some problems.
First being Australian it would normally be a sand beach ... mud, rock are some other kinds of 'beaches'. So I'd add the tag 'surface=sand'.
Second .. arr you have 2 beach areas mapped - confusing. One of them has errors - see way/1009404700#map=15/-37.7795/149.1273 The way cross itself and that is a mistake. I'd simply delete that way - leaving the other one as the beach. The other one is way/1009404701#map=15/-37.7795/149.1273

Keep mapping.

Hi
Would not these 'shelters' be better mapped as covered walkways? highway=footway, covered=yes, surface=paved ???

One member relation for water deleted - not a closed way. This was given to you in your upload warnings...

Boundaries are not fences in OSM.

A relation - boundary is expected to be a closed way, not an open way. So "Vales Point Ash Dam" fails!

Suggest:
tag the way as "barrier=fence" "description=ash retention" "name=Vales Point Ash Dam"

Do:
Delete the relation.

"Is it wrong to have abutting closed ways with identical tags? I am doing this when there are huge areas to help manage the large number of outer ways"

For relations;
If both ways are in the one relation ... then use caution! One of the ways maybe in a different relation (administration boundary, national park for example) and should not be combined.
Some large relations are deliberately split into smaller relations as this makes it easier to manage editing wise.

In both cases it is not 'wrong'. Unless you have a specific reason for doing it, I'd not bother.

Sorry but I'd not an iD user so cannot help there.

Hi,

This change set reverted fully. Meaning all the changes have been undone.
Why? To restore the White Rock Conservation Park boundaries.

You have only made a few edits, so making errors is a way in which you learn. Don't let it worry you greatly. Keep mapping - there is heaps to be done.

The tag 'name' is for the name ONLY. Not for descriptions such as 'tank'.

Storage tanks should be tagged
man_made=storage_tank .. and
building=storage_tank

Hi,
I don't think the Rocky Plains-Eucumbene fire station should be tagged 'health care' ... And probably a similar error with the adjacent building?

It is unlikely to be a 'short cut' ever.
The idea is an 'inner' cannot touch an 'outer'.

This looks to have solved the issue.

Ummm ????
boundary=building? What are you mapping?
relation/12813872.

Still Wrong.
You have to wait a day for OSM Inspector to react.

JOSM validator says:
Errors (3)

Multipolygon relations - Should not have the same way in it twice.

See Way: 1007815262 in relation/13497685 and look at https://tools.geofabrik.de/osmi/?view=areas&lon=151.54298&lat=-33.15497&zoom=17

Suggested solution: Delete the way - it serves no function?

Building:part should not encompass the whole of the building outline...

Way: 1007515114.

No communication... no attempt to fix...

Exactly what is 'Jewells - Redhead - Bennetts Green boundary' relation/13447773???

Jewells, Redhead and Bennetts Green are already in as administration boundaries.

The name tag is for the name only, not name=tennis courts ... that is conveyed by sport=tennis!

See osm.wiki/Names#Name_is_the_name_only

JOSM Validator auto fixes used to fix numerous errors in the Telstra Corporate Centre. E.G. 265 nodes deleted.

relation/13485464 wetland is in error.

See https://tools.geofabrik.de/osmi/?view=areas&lon=129.50471&lat=-14.18659&zoom=17

I expect you would be able to fix this?
