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.
