Nomination of Vice Admiral Mark Hammond AO RAN as Chief of the Defence Force and Rear Admiral Matthew Buckley AM CSC RAN as Chief of Navy
The Submarine Institute of Australia (SIA) welcomes the Government’s nomination of Vice Admiral Mark Hammond AO RAN as the next Chief of the Defence Force and Rear Admiral Matthew Buckley AM CSC RAN as the next Chief of Navy.
Both officers bring superb vision and extensive experience, including submarine command and pivotal roles in progressing the acquisition of conventionally armed, nuclear-powered submarines, to their new roles. This will be vital to assuring the security and prosperity of our nation as they lead our Defence Force and Navy, respectively, at this time of significant global strategic uncertainty.
The Institute also extends its sincere thanks to Admiral David Johnston AC RAN on his retirement as Chief of the Defence Force. His leadership and service across nearly five decades have made a substantial contribution to Australia’s security and prosperity, including leading the Defence Force as Chief of Defence Force and pivotal roles in transforming the Defence Force as the Vice Chief.
“The SIA congratulates Vice Admiral Hammond and Rear Admiral Buckley on their impending appointments and promotions and looks forward to continuing our constructive engagement to support both Defence and Navy by facilitating informed debate on submarine matters,” said Michael Fitzgerald, President of the Submarine Institute of Australia.
