Thanks heaps for that advice, which I've saved. It turns out that there was nothing there anyway, which is a big sigh of relief. But I did get the duplicates I deleted a little further south to show up again using this method. >> I was adding a relation to cover the Bibbulmun Track when I came across >> an area with extensive duplication of ways, which I've been fixing as I >> go along.

I just tread very carefully in JOSM, tentatively deleting ways to see if there's another underneath, and restoring needed things again with ctrl-Z. I remember once needing to delete about 6 duplicates until I got to the last one. In the case of the Bibbulmun Track in this area, it gets complicated because the ends of the duplicated ways don't always coincide.
