Strange but true ..... sent an email asking about this and whether it had any relevance to Victoria (most of it seemed to be directed to WA goldfields) ..... couple of weeks later a copy arrived in the mail (USB drive).
Assumed it was a freebie to review it .... let's just say geology is a complex subject, might be worthwhile if you're heading for WA but still does my head in.
Oh, not sure how they got my address, may have been part of the query form ???
