On 20 December 1999 several ADF intelligence officers attached to the INTERFET force in Dili, East Timor, lost access to a particular intelligence database hosted by the Defence Intelligence Organisation (DIO). In April 2004, following subsequent representations to the then Minister for Defence by one of these officers, Lieutenant Colonel Lance Collins, the Chief of the Defence Force provided the Inspector-General with various papers associated with a redress of grievance by Lt Col Collins. These and other available relevant papers were examined to consider whether the previous inquiry should be re-opened and whether there were any other issues which might be within jurisdiction. On the advice of the Inspector-General the Defence Minister then requested the Inspector-General, pursuant to section 8(3)(a) of the IGIS Act, to inquire into how and why the loss of access occurred.
