My slides for my recent Association for Linguistic Typology Talk on “Standard Average Australian” are now available on Zenodo. The slides are self-explanatory, I think, and the Zenodo page has the long abstract that I submitted to the ALT for conference review. In brief, the talk is about the (largely unreferenced) claims that many Australianists (including me, I should add) have made about the languages of the country.
I am currently writing up the results for submission to Linguistic Typology. Thanks very much to the ALT conference participants, particularly the Australianists I talked to about this.

Hi Sarah, Howard Coate made some tapes, and there is some information in the Laves materials, but not a lot. If you send me an email I can try to help (claire.bowern@yale.edu)
