Hi and welcome to OSM!
Just wondering why you changed the name of this route relation? This section of road is officially called the Pacific Motorway, not the South East Freeway.

Thank you

What's up with the untagged line?

That's a lot of self-intersecting ways...

Thank you - in the meantime I've remapped a few of the creeks and buildings, so these should be correctly aligned now.

Just FYI, DCS NSW Imagery is almost always correctly aligned, so it'd be best to use that imagery.

What imagery source are you using here? It seems very misaligned (~10m or so) from reality.

Hi,
I'm just letting you know that waterways and roads shouldn't share nodes.
Thank you

I got the tags mixed up, actually. The correct combination is highway=construction + construction=residential

Hi
I'm just here to let you know that roads under construction should be given the tag construction=highway + highway=residential instead of construction=yes, because it currently renders incorrectly.
Kind regards,
Solaris

I just noticed that a basketball court area already existed here. In this case, there was no need to add that node in the first place.

Hi, welcome to OSM!
Just letting you know that you don't need to add descriptive names to features (i.e. adding the name "Basketball Court" to a basketball court - the tag itself is enough.
Thank you

Hey,
it's not a good idea to glue footpaths to landuse areas (i.e. sharing nodes between the path and area). It makes it difficult to untangle the two features.

Thanks

Didn't intend to upload this just yet. Comment: "Add more wetlands and water areas"

Hi, and welcome to OpenStreetMap! I'm just here to let you know that you don't have to add descriptive names (such as "vivienda informal") to every house, and they can be left unnamed. Thank you

Hi
You don't need to give every residential area the name "Mountain Creek Estate". A place=neighbourhood node should be added instead, or, since the whole suburb is named Mountain Creek, these residential areas could probably be left unnamed.
Kind regards

Hi- roads (including slip lanes) should only be mapped as separate carriageways if there's physical separation.
Thank you

Why did you add a ton of untagged lines?
