Thanks again for adding the missing bus stops. I added them to the bus route 570 relation. Happy to update more bus routes in case you add more bus stops to the map. If possible, could you add bus route numbers to https://wiki.openstreetmap.org/wiki/Key:route_ref of a bus stop, that makes it easier to identify which stops belong to which route.

Relation 6430221 is a https://wiki.openstreetmap.org/wiki/Tag:public_transport%3Dstop_area, which groups related facilities of a bus stop (of any size). Some renderes make this visible, e.g. https://www.openstreetmap.org/node/4315294270#map=17/-37.68200/145.06999&layers=O . It's also helpful for mapping to make sure all bus stops parts are there and up to date. I added node 7944130164 to it.

Node 3862132530 seems unnecessary, and I rarely add stop_position nodes (The wiki says: "Using a public_transport=stop_position node on the highway can be useful in some rare cases, but is usually unnecessary. The simple and encouraged way to add a bus stop is as a node at the location of the pole or shelter.", https://wiki.openstreetmap.org/wiki/Buses). If someone put them there, I just leave them as they are.

Happy mapping :)
