The leaders of the United States, Japan, India and Australia will meet in first-ever joint talks tomorrow. 

The virtual meeting of the Quadrilateral Security Dialogue, known familiarly as the “Quad”, comes as all four countries see heightened tensions with China over a variety of issues. 

Prime Minister Scott Morrison said the upcoming meeting is “an historic moment,” and that it “sends a strong message to the region about our support for a sovereign, independent Indo-Pacific”.
