I've reverted this maxspeed change at changeset/162268705 - my survey in 2015 was maxspeed=20, Google imagery Nov 2024 still shows maxspeed=20. NSW Speed Data doesn't show any data for this road (not surprising as it's a driveway).

50 zone at my previous survey extended further to east (to eastern side of new motorway). Fixed at changeset/162268559

Maxspeed reverted at changeset/162265114. (Section east of roundabout also reverted - I must have seen a maxspeed on that section of road as I drove across the highway in order to update that maxspeed in June 2024)

I've removed the incorrect ref=B64 from Hobbys Yards Road at changeset/162265114 - I also split the northern end at a likely maxspeed change (maxspeed change indicated on NSW speed data, but I don't trust that source enough to add the maxspeed value for the new way). I've left the maxspeed on the main section alone. Other ways not checked.

Maxspeed for Bylong Valley Way reverted at way/145555798 (from survey)

Princes highway maxspeed reverted at changeset/162265114. I don't know maxspeed of McKoy Street, but I note it's in Victoria (so can't be from NSW Speed Data).

I'm thinking the first option, but I'll ask the Australian tagging list what they suggest.

Maxspeeds correct. I've moved the location of the change of maxspeed about 35 metres east (where the signs are)

From survey Dec 2024:
you split way/897295642 (maxspeed 50 - correct) to create way/1351671479 with maxspeed 100, but maxspeed for the new way is still 50 (not 100), maxspeed becomes 100 just south of Bakers Lane. Fixed at changeset/161744124

I looked at this while reviewing changeset/161364222

Maxspeed south of Rocky River Road is correct. I didn't survey north of here, but NSW Speed Data indicates a change of maxspeed a little north of Everton Vale Road, so this will need a survey. I've split the way at changeset/161763046

Looks like you added a maxspeed to a boundary of a nature reserve (rather than a road). Was fixed by Peter W34 at changeset/129819044

I didn't specifically check this when I drove this section in Dec 2024, but looking at the aerial photography, this looks correct.
