Why is T4 called T4?

At one time ASIO had a specific unit which dealt with a range of technical issues, known as 'T' Branch. T4 was the fourth area within this technical unit which focussed on protective security. Although the branch no longer exists as such, the term T4 became so widely recognised it has been retained by ASIO.

Who can use T4 services?

Clients are typically Commonwealth agencies, statutory authorities or government business enterprises. However, when authorised by the Attorney-General and where there is an identifiable Commonwealth interest, ASIO may provide advice to state and local government authorities and private sector companies or individuals.

Does ASIO charge for T4 services?

Yes, ASIO is required by the Australian Government to recover its costs for providing protective security services. Every job is different and the costs vary accordingly.
