Thanks for noticing. I fixed lots of validation errors before uploading this and the following changeset, not sure how those slipped through. On a new download JOSM only detects the same five currently showing on Geofabrik, and those are fixed now.

There are still issues in other categories but I want to visit some places in person first for confirmation, or focus on other tasks first. But hopefully the error count will start decreasing again!

That's true, especially as more of the roads have been adjusted since this changeset. Maxar imagery is better for the buildings as it's newer, but Bing imagery was better for aligning roads as it was more consistent over long distances, so I didn't want to attempt both at the same time. I will clean up the rest of my mess very soon.

It's not far so I checked - the north site has "no camping" signs now (rehabilitation efforts and a penguin colony). The Scout camp is signposted at the oval entrance (south of the highway along River Ave). It must be the site in the bushland visible on aerial imagery. I've updated both, though I couldn't access the scout camp so the road there is a best guess.

Hi, although you presumably fixed several other errors, you did a bit of damage to a local bus route relation (V2 of relation/4053781/history) with this changeset. It's nothing that can't be fixed, but you might want to keep an eye on that kind of thing in future.
