Genealogical Society of Victoria. We KNOW you have have spotted the offer from the Registry of BDMs because you have rung the Registry and then rung the GSV.
The Registry hoped to have the CD purchase details on their web site before the announcement however as with many technical issues there have been some delays. They have asked that you be patient and keep watching their web site as they hope the information will be there shortly.
Their web site will also include details of the imminent price increase for BDM Certificates - so perhaps now is a good time to get some of those orders in!
