Comment here if you want me to reverted it.

Hi Rohan, I think you may have caused error in the boundary as depicted here

Also can see a red deleted section here that may have caused the error

The Goat Farm Mountain Bike Park is a Capad protected area with boundary gazetted by the government so normally best to leave as it as not desirable to edit from satellite imary.

Hi, there are two post boxes mapped very close to each other here. Are you able to resolve which one is correct and adjust the position more accurately and delete the redundant one.

These links should help…

Hi
It would be more in line with osm practice to shift you business node off the roadway closer to where your business operates from.

Hi
you need to add a node to where the house is that you operate from and add all your tags to that instead of adding your tags to the area tagged as residential.

OSM gets mapped by volunteers so you have to volunteer to add the details to where you want them added yourself.

No response, removed restaurant from rail line. Another by same name seems mapped ok.

No response, removed candy store as moved to new location

Hi
Murray Jackson Drive does not appear on the map here.
Is this a mistake?

This peculiar shape offered to the osm database is not like the building seen in the satellite imagery.

This doesn't look much like the building at this location. You are expected to adjust the random shape offered into a proper shape like the building at this location before uploading.

Hi, you have added address tags...
183 Argyle St, Picton but the Candy store is located at Emmett St, Tahmoor on the map.
If the shop has moved you need to move the shop on the map too.
Just changing the tags makes this location wrong and the true candy store site wrong too.

Ok, I have had a further look now and see by you edits that you wanted the bridges, culverts, etc mapped. Cheers

Not sure what specific errors you are referring to but there is no tag to add to the waterway if it crosses a bridge as it is implied that bridges cross above waterways. Any culverts I add, I always add the layer tag (-1) to the waterway.
As I am adding waterways from a dataset and satellite imagery, it is not possible to add how the waterway crosses the roadways, especially culverts, tunnels and fords and even bridges are not very distinct in country areas. This needs to be done later by other mappers doing surveys. Where others have mapped culverts or ford or combined culvert and ford at some crossings, I have preserved those.
Due to the large amount of data, I would be guilty of not zooming in close to every crossing to ensure the dataset aligns with satellite imagery closely but from doing so much of this I notice I am not alone.
If waterways are mapped crossing road or track infrastructure without bridges, culverts, tunnels or fords it is not an error, it is an indication that no one has surveyed the area yet. If Osmose is picking these up, I would expect them to be considered an alert and not an error.
No doubt that I have made a few errors whilst entering so many waterways but am using the Josm validator before upload and also using Osmi and the WaterwayMap later.
I'll have a look at Osmose too when I finish the catchment.

Hi, welcome to osm.
I noticed the first couple of edits and feel you need a bit of help to do it correctly so that other editors don’t have to follow behind you to fix the building shapes.
You are expected to edit/shift the building nodes to reflect the exact shape of the building. The microsoft building footprints are rubbish and only indicate there may be a building shape here - you then need to fix the shape presented to you before upload and you need to zoom in close to see the shape of the building. Thanks.

Upon further viewing area, it does seem likely to be a gated community segregated from other residential areas.

Hi, Rondanella Drive appears to me to be a usual residential street with normal access to residential housing. Why is it tagged access=private? It is a gated community or similar?

Hi, this looks like a service road to me and not an unclassified road
highway=*

You could add other useful information such as mapped here so that car navigation apps can locate your address way/693134235
