Australia welcomed key partners India, Japan and the United States to Exercise Malabar, a highly visible Indo-Pacific maritime exercise being conducted in Sydney for the first time.
During the 10-day exercise, the four participating navies will test their interoperability in the Sydney and East Australia Exercise Areas.
A range of high-end training will be conducted, including air defence and anti-submarine exercises, aviation, communications and at-sea replenishment between ships.
Royal Australian Navy Ships HMAS Brisbane and HMAS Choules are participating in the exercise, along with INS Kolkata and INS Sahyadri from the Indian side. Ships and aircraft from the US Navy and the Japan Maritime Self-Defence Force (JMSDF) will also test their interoperability.
