Ministerial Communications Network

Overarching Obligations

The Parliamentary Business Resources Act 2017 imposes overarching obligations.
The dominant purpose and value for money tests and specified conditions must be met. See s25, 26, 27, 28.

The Ministerial Communications Network (MCN) provides secure voice and document communications between Ministers, Parliamentary Secretaries, their Departments and a number of other agencies. The MCN is able to pass all information up to and including SECRET level security classified information. The MCN is a closed network (i.e. you cannot dial an extension on the public network inadvertently).

The MCN is provided by Government Network Services in the Department of Finance. Contact the GNS Services Desk for assistance:

  • Phone (after hours): Calls to 02 6215 1800 will be received by a live call answering service and forwarded to the duty technician
