Peter,
I'm sorry you've given up on the mystery call. Here is one last
attempt on my part to convince you the mystery call really is the
distress call of a Green Tree Frog.
I've selected just a short side-by-side comparison, using the
clearest part of Tom's recording that I could find. I've also
presented the recordings at half speed, which is always useful for a
listening test.
This is the soundcloud link:

I've included a Raven sonogram that shows how the harmonics, although
faint, do extend well below 4 kHz (you thought they did not).
I did some broad band noise reduction on Tom's original recording
using RX, and removed the prominent insect call.
cheers,
Vicki
