Kudos to you for making an effort to do some research!! :-)Well, I've spent about as long as It seems wrong that court proceedings or any public enquiry should be suppressed or not at least be made freely available so we can see for ourselves how it transpired without having a cost...making access prohibitive.
Please note that in 90% of cases the Judgement and Summary are not suppressed and are available on AustLII at no cost. It is very unusual for any court case to not appear in the AustLII site. Almost all criminal and civil court cases are published there.
The tribunals related to Steven Unthank v. Watchtower that appear on AustLII were classified "Dismissed" - VCAT tribunal hearings VCAT 1421 and VCAT 1810 If you take time to read the applications and have any basic understanding of law, you will see why it was dismissed due to lack of evidence. The application was nonsensical from a legal stand point, and poorly constructed.
In regards to his court case (which is different than the above tribunals), there is no evidence published on AustLII or the Vic Magistrates Court website, that the case ever happened. So to verify if there was a case, it costs about $20 to obtain the court extract file.
The file is a public sharable document, which will advise whether or not there was a hearing and if there was, the outcome of the case. If there was no case it will be marked Discontinued or similar.
Note: The judgment, not the transcripts, is the key document because it verifies whether or not there was a case or hearing.
