The one marked as secondary definitely doesn't look as such, it looks like a service road alongside a secondary road.

I've also checked another one where road=footpath was changed to highway=footway, however aerial imagery isn't clear enough to determine whether it's a footpath, track, or just old markings in the ground.

There's also the road=centerline that have been changed into road_marking=centerline, which is both a tag that has never or rarely been used in Australia outside of this edit, and is also incorrect in the first instance I checked.

It's also not polite to just make a change like this and expect the local community to just find issues and fix them later. You should instead either try and map it correctly, set it to highway=road to be picked up later, or contact that community.

I think this edit should be reverted as it doesn't look like these changes have all been reviewed, making this an undiscussed automated edit.
