CAP-AU is the Australian Profile of the Common Alerting Protocol (CAP). CAP is an open data standard that is developed and maintained by OASIS, a USA-based open standards organisation. CAP is an international xml encoding standard that facilitates the construction and exchange of all-hazard emergency alert and warning messages between various alerting technologies, systems and networks. CAP enables a single warning message to be prepared for dissemination simultaneously over a wide variety of warning systems that understand and can process CAP-formatted messages.

The standardised alerts produced using CAP can be exploited by a wide range of software applications and technology devices, each capable of processing the message and responding accordingly. Examples of the kinds of sensor and alerting technologies that can interoperate using CAP messages are data networks, landline and mobile phones, internet, fax, pagers, sirens, billboards and electronic road signs.

Early versions of CAP have been in use since 2009 in the various Australian jurisdictions and Commonwealth agencies that are responsible for distributing emergency warning messages to the Australian community. These existing implementations were used as the baseline to develop the common national approach used in this CAP-AU standard.
