Greg Moriarty

Gregory Laurence Moriarty, (born 4 April 1964) is a senior Australian public servant and diplomat, and the current Secretary of the Department of Defence since 4 September 2017.

He was previously the Chief of Staff to Prime Minister Malcolm Turnbull.

Gregory Laurence Moriarty was born in Brisbane, Queensland, on 4 April 1964.

He has a Bachelor of Arts with Honours from the University of Western Australia and a Master of Arts in Strategic and Defence Studies from the Strategic and Defence Studies Centre at the Australian National University.

Moriarty joined the Department of Defence in 1986 and worked in Defence until 1995, primarily in the Defence Intelligence Organisation as a regional analyst.

An officer in the Australian Army Reserve, Moriarty was attached to the Headquarters of the United States Central Command in the Persian Gulf during Operations Desert Shield and Operation Desert Storm.

Moriarty was commissioned as an Army Reserve officer in 1986-87 at SUR and served with SUR until 1988.

Moriarty has been Australian Ambassador to Iran from 2005 to 2008, Australian Ambassador to Indonesia from 2010 to 2014, the inaugural Commonwealth Counter-Terrorism Coordinator from 2015 to 2016, and the International and National Security Adviser to the Prime Minister.

Prior to taking up his first ambassadorial role as Australian Ambassador to Iran in March 2005, Moriarty worked in various positions in the Department of Foreign Affairs and Trade, including in the Papua New Guinea Section and with postings at the Australian High Commission in Port Moresby, as Assistant Secretary of the Maritime South East Asia Branch, and Deputy Leader and Senior Negotiator of the Peace Monitoring Group on Bougainville in 1998.

As Ambassador to Iran, he resided in Tehran from 2005 to 2008.

While in the role, Moriarty travelled to Washington to brief then US President George Bush on Iranian politics, becoming one of a small number of Australian diplomats ever to have briefed an American president.

Campbell was the Commanding Officer of SUR 2007-09.

Moriarty was appointed an Officer of the Order of Australia in the 2024 Australia Day Honours for "distinguished service to public administration in leadership roles, particularly in national and international security".

Moriarty was the Assistant Secretary for the Parliamentary and Media Branch between 2008 and 2009 and then the First Assistant Secretary for the Consular, Public Diplomacy and Parliamentary Affairs Division from 2009 to 2010 of the Department of Foreign Affairs and Trade.

His nomination by the Australian Government as Australian Ambassador to Indonesia was announced in July 2010.

He arrived in Indonesia in late October, immediately prior to the Mount Merapi eruptions and the 2010 Mentawai earthquake and tsunami.

Whilst Moriarty was Ambassador to Indonesia, the Australian Government escalated its border protection policy.

The Indonesian Government opposed Australia's boat turnback policy.

During the appointment, Moriarty recommended that Australians take the time to learn more about Indonesia to set the two nations up for a great strategic partnership that would help Australian businesses to prosper.

From 2014 to 2015, Moriarty was a Deputy Secretary of the Department of Foreign Affairs and Trade.

In May 2015, the Australian Government announced Moriarty's appointment as the inaugural Commonwealth Counter-Terrorism Coordination within the Department of the Prime Minister and Cabinet.

In the role, Moriarty did not have authority to direct the operations of any particular agency, instead being granted authority "across agencies" to enhance cooperation between Australian intelligence and security agencies.

His role was intended to focus primarily on preventing domestic terror threats.

Soon after he began in the role, Moriarty told media that he was "stunned" by the depth and extent of the problem.

After the terrorist attack in Nice, Moriarty was authorised to examine the full range of people of interest who security agencies are investigating for counter-terrorism purposes, to identify vulnerable persons with mental health concerns or patterns of criminal behavior, and examine measures needed to prevent the radicalisation of such people.

In September 2016, Prime Minister Malcolm Turnbull appointed Moriarty his International and National Security Adviser.

Moriarty returned to the Department of Defence in 2017 as the Secretary of the Department of Defence.

He was then appointed the Prime Minister's Chief of Staff in April 2017 heading up the Prime Minister's Office.

Senator Jacqui Lambie slammed Moriarty on his appointment of Kathryn Campbell, central figure in the Robodebt scandal to the $900,000 job as a supervisor for the AUKUS nuclear submarine project.

Although Moriarty claimed that at the time he appointed Campbell there was no Royal Commission, it was already well known regarding her responsibilities for Robodebt and her denials including to Senate Estimates.

Lambie described Campbell's appointment as a disgrace.

Moriarty and Campbell have long ties and both have served in the Sydney University Regiment (SUR) and both have worked out of the Canberra Army Reserve depot.
