A trio of Chinese warships has passed Perth and is now off the coast of Kalbarri in WA’s north. The vessels tracked past Garden Island, Australia’s largest naval base, near Rockingham yesterday afternoon. The base will be the home of the AUKUS nuclear submarines, and right now has a US nuclear submarine visiting for a training program. The Chinese warships have almost finished their lap of Australia after making headlines last week when they conducted a live fire exercise in the Tasman Sea off New South Wales. The vessels are in international waters and are being tracked by Australian authorities.
