Change of maxspeed to 80 for ways 231031199 and 30433850 is correct (I've adjusted position of change of maxspeed from 60 to 80 to a little south of the junction with Claremont Drive)

way/1093024688 looks like a private driveway. Was this maxspeed obtained from NSW Speed Data?
Ways 1028580913, 1093024704, 1028580915 and 1028580906 are maxspeed 70, not 100 (fixed by nm7s9 at changeset/150580954, confirmed by myself May 2024).
way/1062505800 is maxspeed 50, not 100.

Maxspeed of ways 438234295 and 1104548802 is correct, but location of change of maxspeed from 80 to 100 was not in the correct location - I've fixed this at changeset/153204765

Definitely Clarence Loop Road, presumably for the crossing road as well (it's been a while!)

Maxspeed was originally coded as 80, you changed it to 100. The actual maxspeed was a bit of both - I split this way where the maxspeed changed from 80 to 100 at changeset/152452243
