Hey, sorry about the mixup. I had removed the "name:aus" field as I had been unable to find a language code for palawa kani and "aus" was way too broad term. I notice on the other changeset that xtz should be used. Sorry about that! (I had searched the iso639-3 site, but found no hits for "palawa" so I assumed it wasn't ISO recognised). Nothing malicious intended - I ensured the main "name" variable was the dual named version.
