You can probably continue to add them. There's been no address import for NSW yet for various copyright reasons I've not looked into. I imagine if/when that ever gets resolved they'll all (existing NSW addresss) get corrected to whichever format is chosen 🙂

Have not heard of Comaps until now. Sounds like a problem with their search not using underlying data OSM properly.
The "shouldn't be there" seems hotly debated in AU tagging standards, so if it makes that 3rd party app work then that sounds like an ok workaround.
Nominatim, the search on the website, uses the data correctly and displays fine, however.

FYI postcode, state & suburb can be inferred from higher relations and are not required on houses unless there's confusion, e.g. on a suburb boundary

Reverted in changeset/187030101 - you shifted the buildings from correct alignment to an incorrect alignment, not add a building

Redrawn in changeset/186970142

Hi - you should use the `square` (Shortcut = q) feature when drawing buildings so they are more accurate to real life. The majority of buildings have 90/45 degree angles.

Thanks!

Fixed outlines in changeset/186921100

Hi - you should use the `square` feature so buildings are more accurate as they are on the map. Shortcut: Q.
Please align to existing geometries locally. Bing is used here as the primary reference.

The building itself is not layer=1 - that new part you did should probably just be a roof providing it's not enclosed.

If it is enclosed, you'd split the driveway into 3 and join it to the building, marking the middle section as some type of covered :)

Hiya - You accidentally did two of these as `detached` instead of `roof`

Hiya, it's very minor but you should try and keep history where possible (and appropriate) (especially when just redrawing lines). osm.wiki/Keep_the_history

Typo - new node is node/13938342278

Hi - it appears you deleted node/8006662698 (in the correct position, with extra tags) to re-create it with a new node node/1393834227?
Ideally you'd try and preserve history where possible - but this seems like an incorrect edit.

Hi - looks like one of the buildings you marked as building=house isn't a house (way/1527675467). Otherwise looks good

Hi!
You can use the 'square corners' button (Q) to make the corners of the houses into right angles :)

Hiya - if you're just redrawing the line it's better to not delete the old one, just add more nodes & move them as required. Helps keep history better - thanks!

FYI it's better to not delete the old way if you're just wanting to change the shape, so that we keep the history 😀

I don't think that's a trampoline - looks more like a garden with a light? 😅
I also wouldn't be mapping trampolines on residential properties - the wiki says "Do not use this tag for a trampoline in a private garden", most likely because they're not permanent installations.

Yep, Shortcut C :)

Looks good! Just an FYI that you can merge existing address nodes into new building areas & it will preserve the history (and apply the address)
