Australian Government Architecture

The Australian Government Architecture (AGA) supports digital transformation by bringing together a collection of digital artefacts and guidance materials that can be used as a guide to inform its users on how to align to the digital direction of government. 

The AGA content is contributory which means we look for best guidance available such as policies, standards and designs, which provide guardrails for users to follow. In this way it forms a key part of the Whole-of Government Digital and ICT Investment Oversight Framework where agencies can use AGA guidance as a decision-making construct that supports more informed digital investments.  

The AGA is continually evolving to meet the needs of its users by identifying new opportunities, fill in gaps, reduce duplication, share lessons learnt, reduce risks, share and reduce costs and speed up delivery for the benefit of all stakeholders.  

The DTA has recently released a refreshed platform to better navigate and apply the AGA to digital investments, which is accessible via
