GPSed. Have gone off audio file for a confirmed sighting of L. tasmaniensis e.g. https://canberra.naturemapr.org/sightings/4725138. Also sounds like a 2nd species Crinia signifera is also on the recording so I've posted it as a second sighting - see https://canberra.naturemapr.org/sightings/4734169.
The 2nd frog species becomes more noticeable about 20-30 seconds into the recording. I now see that you've picked that up and have confirmed it as C. signifera. Thanks.
