Alan & Jake,
Just to clarify the situation in Victoria with the rego records.
VICROADS do still hold the registration records from the pre computerisation era (mid 70s). The problem is twofold.
Firstly, and as indicated previously, the privacy laws have completely restricted the information available in relation to names and addresses. Whether you think it is right or wrong, there are very few exceptions made.
Secondly, even though many of the older records still exist, even if it was available, the information has not been transferred to database.
The information that the AOMC has access too ARE NOT registration records. From 1934 to full computerisation in about 1984, the Victorian authorities kept two sets of information. The registration records which referenced registration numbers against owners details, and the engine number records which referenced engine numbers against registration numbers. Confusing isn't it!
The AOMC has access to the engine number records. If you know the engine number, it is therefore often possible to determine engine changes and dates, changes of registration etc. Unfortunately - no personal details. If you're interested in the information from these records the fee is $25 and you can get a copy of the request at -
