A very long, drawn-out buzz ending in a stutter.
This is my best guess on ID. A few present, calling from branches of Eucalyptus, Melaleuca, and Casuarina. Large breaks between calls and individuals seemed to remain locationally static. Too high up to locate or net and I didn't know how to bring them down with clicking.
See https://inaturalist.ala.org.au/observations/4970472 (this record split from that one).
Sounded like one or 2 individuals calling from banksia species in the dune.
4 males still calling. Excuse the phone quality of recording and the annoying teenagers. In life their calls were strong and they moved frequently
