I understand it to be as follows:
The State of Victoria set up an Inquiry into the Handling of Child Abuse by Religious and Other Organisations and this was done through the Victorian Parliament. There were hearings and submissions with Unthank making an appearance and being restricted to thef 'terms of reference'.
The Federal Government decided that the matter was of such great importance that a Royal Commission was required and announced they would set one up. A Royal Commission has a lot of power and it is generally more than that of a judge. As mentioned in the article above, they may be able to void confidentiality agreements and have suggested they will do so. Public hearings for this Royal Commission have not begun and no dates have been set. It is expected to take a significant amount of time and this is likely to mean years.
The Victorian Inquiry is still ongoing. This is a summary of a couple of media releases from the Victorian Parliament
13 NOVEMBER 2012 — Media comment regarding announcement of Royal Commission
From Ms Georgie Crozier MP, Committee Chair
"The Inquiry's work thus far has bought to light important revelations that have been key to the Federal Government deciding to call a royal commission."
"From our part, a significant amount of work has already been undertaken and there is more we can achieve but we obviously need further detail of the federal inquiry including its terms of reference before making any changes to our work."
12 NOVEMBER 2012 — Media comment regarding announcement of Royal Commission
From a spokesperson for the Committee
"The Premier has tonight released a statement saying that the Victorian Government will work to appropriately bring together the work of the Victorian Parliamentary Committee's inquiry and the federal inquiry."
"The Committee has already undertaken a significant amount of work and until we receive further detail of the Commonwealth's
approach, we will continue to progress our work on this important issue."
