Indian warships began a week-long naval exercise off the coast of western Australia.
The second AUSINDEX exercises are aimed at increasing interoperability between Australian and Indian naval forces, executing complex naval manoeuvres.
The first AUSINDEX was held in the Bay of Bengal in
2015.
As the only countries with the largest Indian Ocean coastline, Australia and India are natural partners in maritime security, particularly in the region where India has its greatest strategic interests.
In the past couple of years, the two countries have ramped up security cooperation beyond mil-to-mil exercises.
