It's a good suggestion and I will inquire next time I'm there. Trouble is, I'm a Victorian but currently living in regional NSW. Most of the deaths I'm trying to verify were in Victoria. :(
If I have no luck I'll hit the State Library next time I'm in Melbourne.
Regretably, the responses to my 'Get Help' request were underwhelming (to say the least). I don't think the help-desk people actually understood the issue.
