Hi Ryceman3,
This is the first time I have posted as I can't comment about trees being a total novice (!!) but pots I can.... a lot of the TAFE's have either closed or are in the process of closing down their ceramics programs. Some Community Houses do run courses although many of them will only use and fire earthenware clay so your wife may need to make enquiries first if she wants to use stoneware.
She can also make enquiries, however, at some of the following places who do run pottery courses...

There are a number of potters who teach classes too - Gary Healy in Balwyn springs to mind - 0468 814 431
Camberwell Community Centre run classes, and I believe Jill Anderson still runs classes at Glen Eira College.
There are bound to be lots more but these sprung to mind....
Hope that helps
