Are you sure it's Rocky Hill Track, not Wandilla Track?

Please don't vandalise openstreetmap, useful contributions are welcome; this is not.

Collarbone Creek Downhill, this seemed to be called "Grand Canyon Downhill" from looking at it today - is this an older name?

Ah nice work. I rode from Morgan to Eudunda back in November, keep meaning to map out most of the buildings/businesses/drinking water/etc.

This removes a well established park and removes tagging as a recreation ground on many of the others - that's not right.

Hello!
Thank you very much for your contributions to OpenStreetMap!
I reviewed your changeset on OSMCha and found some errors or elements
that could be mapped in a better way. Feel free to message me
to know more about it or visit http://learnosm.org/ to get started.

With the footpaths, it might be best to tag them as 'pavement'. Its a bit of a funny bit of modelling with OSM, trying to decide when a footpath is 'part of' a road or seperate from it.

https://blog.mapbox.com/improving-sidewalks-globally-in-openstreetmap-216bf34cca22 discusses it a bit

Ah, nice work with the buildings in Semaphore. I've been chipping away at between West Lakes and Outer Harbour for a while, keep up the good work

That... should probably be reverted. Orrong Road as 60? Maybe, but the rest?

I think its meant to map the vineyard, see the "Ron Gol" farm POI further south.

Nice work on the housing! Another new user in your area has been doing a bit around Flaxmill Road/Southern Expressway. I reckon we could map out all of Christie Downs between flaxmill/gulfview and the river in the next few days with a bit of collaboration!

Mead street trail seemed quite different on the ground - is this from survey?

Nice work over the past few days :)

With building tracing, its a bit more tedious but you want to try and match the roofline shape as much as possible - take a bit of a look at say City of Geelong.

Luckily for new developments like this, a lot of the housing is actually built to the same design, so you can copy/paste/rotate a few common house traces and get good coverage.

Keep it up, and if you are out and about in your neighbourhood; running StreetComplete on your phone is a good way to start getting the next level of detail (addresses, building levels, etc)

With a lot of these, whacking '50' indicates its a maxspeed from a sign; but there's another option around "there is no sign" which applies the 'default maxspeed for the country' which is a bit more useful if it changes by legislation.

These seem to be residential housing

Aitken Boulevard is visible now on Esri imagery at zoom 19, appears to be dual direction road

Ugh, when I added it originally it would have been for the boat shop on the corner of Tapleys/Old Port Road, and I've assumed it the commercial area stopped at Hardy Street

Worth marking landuse=construction?

At this point, I'm inclined to suggest reverting - this area had a whole lot of other fictional edits around ~2 years ago, its odd that it attracts them or its the same user with a new account vandalising.
