The United States and Australia have signed a first-ever bilateral agreement that allows the U.S. Cyber Command (USCYBERCOM) and the Information Warfare Division (IWD) of the Australian Defense Force to jointly develop and share a virtual cyber training platform.

The two countries' departments of defense will achieve this by incorporating IWD's feedback into USCYBERCOM's simulated training domain known as the Persistent Cyber Training Environment (PCTE).
