Australian Government Architecture (AGA)


Overview of AGA

The AGA aims to assist in the delivery of more consistent and cohesive service to citizens and support the more cost-effective delivery of ICT services by government, providing a framework that:

  • Provides a common language for agencies involved in the delivery of cross-agency services;
  • Supports the identification of duplicate, re-usable and sharable services;
  • Provides a basis for the objective review of ICT investment by government; and
  • Enables more cost-effective and timely delivery of ICT services through a repository of standards, principles and templates that assist in the design and delivery of ICT capability and, in turn, business services to citizens.

The AGA is being released in a series of versions as the content is developed. In developing the AGA, Finance has adapted the established and proven Federal Enterprise Architecture Framework (FEAF) developed by the United States Government. This framework is being used in a number of other countries as well as some State Governments in Australia. The framework and these reference models have been endorsed by the Australian Government’s former Chief Information Officers Committee. The diagram below illustrates the structure of the AGA:
