BirdLife Australia has recently updated it's so-called "Working List of Australian Birds", which is largely based on HBW/BirdLife taxonomy, to version 2.0. While I would not recommend this hybrid list as a taxonomic source, it was interesting for a few omissions; firstly BirdLife Australia declined the split of Rufous-bellied Spinifex Pigeon and lumping of South Island Pied Oystercatcher, and published short opinions against these in the accompanying documents. Secondly the list contains this little nugget regarding Masked/Black-shouldered Lapwing:

Species from email from N.Collar (2014), contra del Hoyo et al. (2014) noting that this taxon will revert to subspecies at next revision of BirdLife International Checklist
