I updated the tags to conform to wiki guidance to erase the splash of meaningless green text on osm.
This can be further refined by using a destination relation which I will leave for others.
information=guidepost
osm.wiki/Relation:destination_sign

information=guidepost
tourism=information
information=guidepost
are required.
leisure=park is wrong

I am not familiar with mapping signs but these links may help
tourism=information
traffic_sign=*

Hi, welcome to the osm. It is unclear what you are adding to the map here seems not to be the usual manner in which info is added to the map.

I expect most of us have had to abandon very large editing sessions from time to time for various reasons, including getting hopelessly lost in the complexity of the data in some places.
We also would have used some copyrighted sources whilst learning the rules, but they are unable to be used without explicit permission from the copyright holders.
Some open data sources also require explicit permission to use, depending on the licence.
These things are of part of the process of becoming familiar with the osm.
This is a useful site to check if we have obtained permission to use...
osm.wiki/Australian_Data_Sources
I recently learned when copyrighted material has been used to add to osm, it is reverted and then redacted.
The osm Data Working Group do the redactions but anyone can revert problem edits.
I suggest contacting the Data Working Group via email at data@openstreetmap.org
osm.wiki/Data_Working_Group
with a brief explanation and a link to the changesets as the changeset comments are informative.
They can then make a judgement and if necessary do both the revert and redaction.
If you prefer that I or @tekim does this instead, that's fine.
...and keep on mapping :)

Bing Maps is also not suitable as a source for osm.
osm.wiki/Bing_Maps

This changeset followed this discussion on the community forum 'https://community.openstreetmap.org/t/watercourse-name-appears-incorrectly-mapped/111268/4

fixed, please check

Hi, why have you chosen not to follow the house outline when mapping this?The usual method is to draw an accurate representation of the house outline using satellite imagery.

Hi, this section of fence is joined to the middle of the road for a couple of stretches.
way/894225650#map=15/-24.6479/145.9404
I can't really identify the fence line on imagery but if I strain my eyes beyond reason there is a straight line visible near west of this road which is probably the correct location.

Also note that allhomes.com.au is owned by The Domain Group and is a copyrighted and not able to be used.
See osm.wiki/Australian_Data_Sources for sources we have explicit permission to use.

This blue indicated area is involved too…

…and the osmi errors…

Hi, I thing you may be triggering a few osmi errors. Please consider getting familiar with and using the Josm editor if you are intending to fix boundaries and multipolygons.

It must be this one I expect...

If you decide to ask on the community page it would help to provide the osm url from your browser showing the particular area of concern so that others can see clearly what you concern refers to and be specific in your description.

Hi, the changeset comment is not really suitable for making a query of the mapping community.
It is meant to just describe what you have mapped in the changeset you are uploading to help when others want to see the history of mapped objects or a brief summary of what was done in a particular changeset.
The question about the mapping of the bay would reach the right audience if you asked on the Oceania Community page at https://community.openstreetmap.org/c/communities/oceania/73
I think the user login is the same one you use when editing.
Coastlines are mapped to the mean high water line so on a satellite image would often appear near the high tide debris line. If this is not a suitable reason for the problem you see please ask on the community page.

You tagging is correct but for consistency your unit may be better tagged as addr:housenumber=3/25 to fit with the other mapped units.

Hi, if you change to Ersi imagery you will see the house though the shape is not sharply depicted.

This shows where the bench was originally mapped ...

I think this was done accidentally and I have reverted in this changeset
