Thanks for your comment, Rob. I am also still not happy with the bird's
structure for L. f. fuscus. Maybe a large male? But where does the
dark-speckled iris come from?
In the European discussion graellsii and intermedius were mentioned. First, I
thought (but I don't know for certain) that the Broome bird's moult doesn't fit
these two taxa. Second, I remember a paper by Visa Rauste in Limicola, in which
he says that heuglini and graellsii/intermedius are more or less inseparable.
There is also an interesting paper by Chris Gibbins (Birding Scotland 7 (4):
153-186).
However, given the known (or at least speculated) migration routes, the
occurrence of graellsii and intermedius in Australia would be very unlikely -
in contrast to heuglini and fuscus.
Cheers,
Nikolas

Discussion Update
D'no reason for it to be fuscus fuscus' or did you mean "no reason for it not
to be fuscus fuscus"It still looks wrong structurally to me for fuscus fuscus
(I agree with Nicolas Haass on this & his views!). It just looks too heavy and
not slender enough to me! But perhaps its on the upper end of the scale - a
large male or something? Time will tell!
