Thanks Nikolas,
I see there being two conflated issues here.
One is the ongoing taxonomic revisions that affect species that
regularly occur in Australia - species that either breed in Australia
or are regular migrants/visitors to Australia.
The other is the official recognition of observations of vagrants in
Australian territory. These are often only made in external
territories and infrequent / "one-offs" - the "recent sightings of
Asian Stubtail, Eastern Crowned Warbler" you cite are a good case in
point.
IOC lumps and splits is the key issue for twitchers who want to keep
their lists up to date. The addition of vagrants to the Australian
list is a separate matter.
Regards, Laurie.

Hi Paul,
Yes, as I said, the OZ-list is a dynamic list as well and it is
meant to follow the latest IOC decisions (currently 3.1). But this
doesn't only mean that it will be frequently updated with the latest
IOC decisions but also with additions to the OZ list such as the
recent sightings of Asian Stubtail, Eastern Crowned Warbler...
Therefore there may be a (slight or not so slight) delay in the
dynamic.
Cheers,
Nikolas

Thanks Nikolas, that was the list that I was using – however, now I
have some further concerns.
A number of people have told me that the Quail-thrush splits I
mentioned have been accepted by IOC in the latest release. On
checking the BARC spreadsheet, I note that these are not listed as
official splits in that list – which is based on IOC 2.9 – whereas
they are split in the latest IOC 3.1 list that I have downloaded
from http://www.worldbirdnames.org/
So, this begs the question – IF Australia is to use IOC going
forwards, are we to use the most current IOC checklist, or do we use
the checklist based on IOC 2.9 with some amendments posted on the
BARC page? In my opinion, if we’re to use IOC we should be using the
current IOC checklist.

Hi Paul et al.,
An IOC-based OZ list compiled by David James is on the BARC website:
http://www.tonypalliser.com/barc/barc-home.html
Similar to the IOC list itself, this one is a dynamic list. So, keep
checking.
Cheers,
Nikolas

Subject: [Birding-Aus] C&B vs IOC taxonomy
Hi birders,
Following is my analysis of the splits that are supported by IOC but
not by
Christidis and Boles:
Antipodean Albatross (split from Wandering Albatross)
Northern Royal Albatross (split from Royal Albatross - and Royal
Albatross
renamed Southern Royal Albatross)
Campbell Albatross (split from Black-browed Albatross)
Salvin's Albatross (split from Shy Albatross)
Chatham Albatross (split from Shy Albatross)
Indian Yellow-nosed Albatross (split from Yellow-nosed Albatross - and
Yellow-nosed Albatross renamed Atlantic Yellow-nosed Albatross)
Western Grasswren (split from Thick-billed Grasswren)
Hornbill Friarbird (split from Helmeted Friarbird)
Swan River Honeyeater (split from White-naped Honeyeater)
And the following are proposed splits, I believe:
Western Quail-thrush (split from Chestnut-breasted Quail-thrush)
Nullabor Quail-thrush (split from Cinnamon Quail-thrush)
Western Shrike-tit (split from Crested Shrike-tit)
Can anyone with more taxonomic experience than me please confirm these
splits? Have I missed any splits that anyone knows about? Also, are
there
any lumps under IOC?
