Osm maps the roads and tracks as they exist on the ground and I have remapped this area to reflect that.
I see with reference to the DCS NSW Base Map layer that is available to us in the editors that the road reserve and property boundaries may be in conflict with part of Frenchmens Road. 
You will need to resolve this with the property owners and local council if a problem exists here. When and if there are changes made to the road and track layout then the new situation can be mapped. 
I note that Waterfall Road is signposted and properties are addressed using this name. I also saw that Frenchmens Road is signposted as Frenchmans Road but that osm is using Frenchmens Road as in source:name=LPI NSW Base Map.
I also fixed the wood multipolygon.
