Australia taking cyber fight to Isis, Malcolm Turnbull to confirm

Signals directorate is supporting coalition military operations in Iraq and Syria, PM will tell parliament

The prime minister will tell parliament on Wednesday that Australia's cyber capability, through the Australian Signals Directorate, is being deployed offensively to support coalition military operations against Islamic State in Iraq and Syria.

Malcolm Turnbull will make a security statement at noon addressing directly the sensitive subject of Australia's offensive cyber capabilities - while the minister assisting the prime minister on cyber security, Dan Tehan, will use a separate outing at the National Press Club to argue that, domestically, Australia needs to step up its preparedness against hacking and malicious cyber-attacks.
