A selection from about 30 000 recordings made 2012, 2013, 2014 and 2016 in New South Wales.
My personal view…

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.
