Hi, you've tagged https://www.openstreetmap.org/way/450150184 as if it's Humbug Scrub Road, it's actually part of an administrative boundary.

Same goes for https://www.openstreetmap.org/way/450150187 and https://www.openstreetmap.org/way/461801765 where you've added the maxspeed tag on ways that are part of a boundary.

I think it's best to revert this and to apply these changes again on the correct ways, since you've moved the boundary ways.
