Well, if you’re going to think aloud, think big, I suppose.
I just ran across a late-2010 thread at the site of the Melbourne Unitarian Peace Memorial Church about the prospect of a Unitarian Universalist seminary in Australia. Since the number of Unitarians and Universalist in Australia and New Zealand seem to be in the hundreds, I would counsel something a bit more modest at first — a organized lay peaching course or an intensive history or theological seminar within one of the theological faculties — but the post and comments, while few, should encourage those interested in ministerial formation.
