Gday JBH & Co!
I believe that we have a potter in Oz named Pat Kennedy. Can't say that I'm particularly familiar with his/her(?) work, but it is a name I have seen thrown about a bit.
Here, for example - I believe the pot pictured in the 2nd and 3rd pics is a Pat Kennedy creation.
Thanks and good luck.

BTW: Dr Roger Hnatiuk is the convener of the Oz Native Bonsai study group(s) listed in my signature.
