I removed the tags that were on the outer way of the multipolygon for Pine Lake. Tags are on the multipolygon instead as well as some tags on the inner.
This allows the islet "The Island" to render correctly

Why is this mapped in the middle of nowhere in trhe southern Northern Territory instead of where the vtags suggest in Cranbourne East, Victoria

I shifted your cafe edit from the footway to nearest building where a cafe was already mapped.

name= xx is not correct
addr:housenumber serves that need

Should this be landuse=commercial then
landuse=*

ford deleted

osm.wiki/Names#Name_is_the_name_only

Please only name things that are sign posted as such.
Simon-Coral footpath seems an unlikely real name.

Hi, the Electoral district of Hawthorn appears to have only 3 sides
way/1184137009

Hi, you have added ford=yes to the entire length of Chainsaw's brother.
You should split the way each side of the ford and add the ford=yes tag to just that small section where the ford is.

Consider using the name on the street sign as
name=Hector Road plus for example
old_name:1921-1932=Coolgardie Street
name=*

Hi
I have reverted both of your edits of items that don’t exist at mapped locations

This gift shop also seems to not exist at this location.

Hi
why have you added a bank to the rural area of Yarrowville and also tagged it as being on McDonnell St in nearby Raby?
This is a public map.

Hi,
I have edited the phone number format using these guidelines
osm.wiki/Australian_Tagging_Guidelines/Australian_features#Phone_Numbers
But I notice that the website gives a different number....

Telephone Savannah 0481 210 948

There is provision to add the affected hours to turn restrictions
osm.wiki/Relation:restriction

Is this a private business or just to mark your home?

Hi, you may wondered why you edit does not appear on the osm map.
You need to use specific tags to use osm effectively…
healthcare=*
For a gp practice see this sub link
amenity=doctors

Hi, do you occupy all 5 levels of this building? If not you should add a node within the building footprint and add your business details, including unit, level, etc to it

You are expected to place your business over the building you operate from instead of a random house or in a park. If you are an online only business you should not list it on the OSM as it is not a business listing service.
