I welcome the Prime Minister’s announcement today that Meghan Quinn will become the next Secretary of the Department of Defence.
Having served as Secretary of the Department of Industry, Science and Resources since 2022, Ms Quinn brings with her a wide range of experience across the public sector, including positions at Treasury and the Department of the Prime Minister and Cabinet, as well as in the private sector.
With Defence being one of the largest federal government departments, Ms Quinn’s experience in public administration and strategic leadership means she will be well placed to lead Defence into the future.
Ms Quinn will make history as the first woman to substantively lead the Department of Defence, and I know that alongside our recently-announced leadership changes within the Australian Defence Force, she will bring a wealth of experience in this role.
I would like to once again thank Greg Moriarty for the contribution that he has made to the defence and security of our nation, and I look forward to working with him as Australia’s next Ambassador to the United States.
