Daniel, I can send you what little triplet information I have. It looks like they've simply changed LCN 60 from SD to HD without changing the triplet. That's certainly the case for Canberra Black Mountain.
For the other regions I have scan data for (Albany WA, Ballarat, Newcastle, Orange), they've simply switched one of the Prime7 SD simulcast services from SD to HD without changing its triples (and presumably, since I think Prime7 HD is uniformly on LCN 60), it was the that LCN that was changed over. I don't have the triple->LCN mapping for any of those regions.
