A selection from about 30 000 recordings made 2012, 2013, 2014 and 2016 in New South Wales.
My personal view…
Still many recordings are not identified; some will perhaps be…

The recordings are made with Pettersson D500x.
The graphics are shown as seen in BatSound software.
I try to show all with a 2 sec. recording and from 0 to 100 kHz. To show important details, single calls are presented as a 0.2 sec wide spectrogram.
Use the media player link above the graphics to listen to the sound, expanded ten times.
The original recording (mostly 4 sec) can be downloaded via a link below the graph.
The location can be reached via the Google Earth link.
