Apologies - I grabbed the SEVENTH edition of P&K - it has the Ringnecks as
two separate species.

Also, I should have said Sunbury, VICTORIA...

"We are a little confused though - According to Pizzey & Knight (including
the Eighth Edition) there are two species of Ringneck - The Eastern or
Mallee Ringneck and the Western Ringneck or Port Lincoln Parrot. According
to The New Atlas of Australian Birds there is just one species - The
Australian Ringneck. Does anyone know which is correct? Presumably if there
is only one species, then our sighting of a "Western" Ringneck is less
interesting - although the bird definitely has the Western Ringneck plumage
(according to the image in Pizzey & Knight)."

The Eight Edition of "(Menkhorst) Pizzey and Knight" does not describe two
species of Ringneck.
That edition of the field guide has combined the previously described two
species into one species 
with four subspecies/races. Each of the races is given a common name with
the nominate race being 
"Port Lincoln Parrot" or "Ringneck". P & K does not name any of the races as
"Western  Ringneck" 
however HANZAB ascribes that appellation to the nominate race (Port Lincoln
Parrot).

Since the publication of "The Taxonomy and Species of Birds of Australia and
its Territories" by the 
RAOU in 1994 the 'official' view has been that there is only one species of
(Australian) Ringneck 
with four subspecies. It will be interesting to see if that remains the case
when the next version 
of that publication is published later this year.

Assuming that the "Sunbury" referred to by Paul Dodd & Ruth Woodrow is the
one in Victoria, 
Australia (the posters' email address could indicate otherwise), the
sighting is undoubtedly of an 
escapee or the descendant of an escapee.
Determining the degree of interest engendered by such a sighting would be a
somewhat subjective 
process. Personally, I would be saddened to think that a bird which was
possibly bred in an aviary 
had been released or had escaped into the wild. However, that sadness would
be lessened to a degree 
to if it appeared that the bird was surviving well in the "wild".
It would appear from the maps and notes in the first Atlas of Australian
Birds (1984) and the Atlas 
of Victorian Birds (1987) that populations of Port Lincoln Parrots
(Barnardius zonarius zonarius) 
have been established from aviary escapes.
