Hi Patrick et al
I haven't read the Joseph paper but the original Jonsson paper that sparked it
is available here from a link on birdforum:

This split came out of the blue since WA and SA birds have been lumped under
the same subspecies (fuliginosa) for some time, though Schodde & Mason do note
WA birds can be distinguished as 'regional form' occidentalis. Not much
distinguishes these two so its probably fair to call this a cryptic species,
but the males have a more lemon-yellow breast and greyer tail with a smaller
back tip. The females are paler and plainer, with a paler back (no contrast
with the crown) and paler buff on the belly.
The separation occurs at the Nullarbor proper so a quick check of atlas data
suggests this will not be a WA endemic as there a few records on the SA side of
the WA/SA border that should be this new species. So an 'almost endemic'!
Cheers
