The record was by Tom Lowe, who certainly knows birds - including waders,
who saw Pied Oystercatchers on a bare mud island at the western end of the
saline Lake Tutchewop in September 1977, and watched them for ten minutes at
a time. The circumstances: birds seen on a couple of occasions in fine
weather at c.100 metres with 10x50 binoculars by an expert observer familiar
with a fairly unmistakeable species, would seem to leave little room for
error. The record did attract an URRF (unusual record report form) which
was filled out and accepted as confirmed.

It does appear to be the furthest record from the coast, Australia wide, at
least according to the Atlas. I have no idea of what the weather conditions
were earlier - maybe storms that pushed them inland.
