Earlier in April, I went on TDY (temporary duty) from U.S. Embassy Canberra to U.S. Consulate Sydney to cover a short staffing gap. Although I was only in Sydney for a week and a half, it was a fantastic opportunity to help out the mission while learning how to do a different job. And of course, I was able to spend time in one of my most beloved former home cities – and visit old haunts, old friends, and even my postgraduate alma mater, Macquarie University. It was rewarding, it was fun, and it was even a little bittersweet.
