Hi you asked for a review, so I'll provide some feedback.

Overall it's good, just keep in mind that a name is only something as signposted or otherwise generally known as, not a description see osm.wiki/Names#Name_is_the_name_only. So "Walking Path" is probably not the name, so best to leave it blank.

You've added this tag to every node of the way, it looks like you've used select all in JOSM. Could you please fix this?

I didn't hear back on this so I've updated this again so that name:en is only the English name so that you can distinguish the English name vs. the indigenous name.

I noticed you've added "Old Bells Line of Road" to https://osmlab.github.io/osm-deep-history/#/way/37627194 on a recent survey I found this one named "Newnes Forest Road" https://www.mapillary.com/map/im/k1mhrLMDQy3dwnWHk-fDkg

Do you have any other local knowledge about this road name, I'm trying to decide if I should update it to the signage I saw...

You've added noname=yes to a bunch of notes along the ways eg. node/4073250116/history I assume this was a mistaken select all in JOSM, just a hint to be extra careful when making mass edits like that.

Hey I've fixed the helipad you accidentally moved in this changeset changeset/29445911

I'm planning on cleaning up this intersection to remove the parallel ways which have no separation apart from paint on the ground, to use lanes and turn:lanes. Turn lanes shouldn't be a separate way they should use turn:lanes instead.

There's nothing wrong with single ways that enter the roundabout, in fact I'd say this is preferable than splitting the ways for a pedestrian island which I think is not necessary and incorrect.

Per https://lists.openstreetmap.org/pipermail/talk-au/2019-October/013032.html could you chime into the discussion please? Either here or on the mailing list.

direction=clockwise doesn't make sense on a lookout, it should be a number/cardinal direction or range. direction=*

Is this also information=office

It would be great to documented this tag on the wiki. Currently the only documentation is for the tag you removed osm.wiki/Proposed_features/aerobridge

When using a dual name "name:Mrs Macquaries Point / Yurong", then we need "name:en" to equal "Mrs Macquaries Point" so you can break down that dual name into each language.

It looks like you've changed that back here http://osmlab.github.io/osm-deep-history/#/node/13816944

If you check the history of https://osmlab.github.io/osm-deep-history/#/way/179207161 it looks like you've incorrectly removed the oneway tag, which was then fixed by someone else, and then you removed again, and it was fixed again.

Was this a mistake or intentional?

You've accidentally dragged the bicycle parking see https://osmcha.mapbox.com/changesets/68816300/, however I've fixed this now in changeset/75209417

To be honest I couldn't find this documented anywhere on the wiki but now I see https://taginfo.openstreetmap.org/search?q=destination%3Aref%3Alanes is more popular.so I've added some documentation to the wiki.

Fair point, although I wouldn't consider it a lane, I guess the access:lanes=no implies that it isn't a lane. I've changed it back.
