Defence Minister Peter Dutton marked the 75th anniversary of the Australian Signals Directorate by opening a new facility for the signals intelligence agency in Canberra last week.

Mr Dutton said intelligence and cyber experts would come together under the one roof to provide a robust strategic cyber capability.

Staff from multiple government agencies will work at the new Majura Park offices, including ADF and law enforcement personnel.

Mr Dutton recalled the ASD’s history during his address, from decoding enemy radio signals during WWII to offensive operations against cyber criminals today.

“Cyber is the new frontline,” Mr Dutton said.

“There is a lot that goes on within the ASD that Australians will never hear about,” Minister Dutton said.

Mr Dutton said Australia was in the cross-hairs of malicious cyber activities and investment in agencies such as the ASD would help keep Australians safe online.

The announcement came days before the opening of an exhibition on April 1 at the National Museum of Australia showcasing the people, stories and artefacts from the ASD’s history.

The exhibition is one of a number of events taking place this year to mark the organisation’s anniversary.

Director-General ASD Rachel Noble said the exhibition, named DECODED, provided a rare insight into the secret workings of the agency.

“So many of our former and current staff have never been able to tell anyone much about the work they have done,” Ms Noble said.

As part of the anniversary, records from the Vietnam War and Malaya Emergency are set to be declassified this year.

Secret communications about SAS training in Vietnam could be included in documents soon to be released.

Ms Noble said the anniversary would reach a high point with the publication of a book next year detailing the history of the directorate, from WWII to the Vietnam War.

“Our book and the exhibition are a celebration of their amazing work over 75 years, and I’m sure for more than 75 years to come,” she said.
