Sir Angus began as a helicopter pilot in the Royal Australian Airforce in 1972 and rose through the ranks to eventually become Chief of the Airforce in 2001. Four years later, in 2005, he was promoted to the pinnacle of the military hierarchy, Chief of the Defence Force. He served in this role for 6 years, overseeing Australia’s military operations in East Timor, Iraq and Afghanistan.

Following his ‘retirement’ in 2011, Sir Angus’ contributions have broadened to include several board positions in a variety of organisations, from military to humanitarian causes.

In 2014 he headed Australia’s efforts, first to find the missing Malaysia Airlines Flight 370 which disappeared and has still not been found, and, following the Malaysia Airlines Flight 17 disaster over the Ukraine, Sir Angus was appointed to help recover, identify and repatriate Australians killed in that incident.
