I'm a member of the Australasian Mining History Association and am in touch with Mel. I'll certainly be sending something to him after completion, and have promised to send Dave Linton something also, back in 2012, when I started all this.
I'm registered with Cardiff University, under supervision of Professor Bill Jones, whose major field is emigrants from Wales - you may be familiar with his work on the Welsh communities in Ballarat.
When I get a chance I'm also going to follow up my coal mining relations, who left Hirwaun for first Como Lower coal mines in Colorado, and then for Colliefields, WA, before ending in NSW, first in Thirroul and then at New Greta. They were John Evans, his son, T J Evans, and following John Evans as manager, his wife's cousin Rees Bevan. But first let me finish on my George W Hall!
