Oates and Oates (1970:65) say that Douglas found one speaker who claimed Bulinja (W43) was the original language of the Geraldton area. Douglas (1964) mentions this name. According to Clarrie Cameron (2009 p.c. via Henry Fraser), Pulinya is an old name for Nhanhagardi A93. Consequently, Pulinya is listed as unconfirmed.
Note that the identity of Nhanhagardi is also uncertain. See and use Nhanhagardi A93.
Speaker numbers were measured differently across the censuses and various other sources listed in AUSTLANG. You are encouraged to refer to the sources.
Speaker numbers for ‘NILS 2004’ and ‘2005 estimate’ come from 'Table F.3: Numbers of speakers of Australian Indigenous languages (various surveys)' in 'Appendix F NILS endangerment and absolute number results' in McConvell, Marmion and McNicol 2005, pages 198-230 (PDF, 2.5MB).
