Long time lurker, some time editor. It is my understanding that marked "turn right only lanes" are not cause to create divergent ways. These should be tagged using the "lanes" key as per https://wiki.openstreetmap.org/wiki/Key:lanes
Creating divergent ways is considered "Tagging for the renderer" as the documented separation is not physically there. The first one, in WA, appears less of an issue to me. Perhaps the separation nodes could be closer to where the ways actually diverge, somewhere around the mid-point of the dashed lines, rather than at the start of them. The second one, near Canberra, has clearly diverged ways most of the way along the bridge. This intersection in Melbourne could potentially serve as an example: https://www.openstreetmap.org/#map=18/-37.93265/145.15653 Where there are actual medians between lanes, the ways separate, otherwise, they do not. Hope I haven't spoken out of turn. The views expressed above are my understanding of the guidelines with respect to mapping what is actually there.
