Australia revealed plans to build a new naval base that will maintain and resupply nuclear submarines from the United States and the United Kingdom, in addition to improving its security defenses in the Indo-Pacific region, at a time when the West is looking to counter Chinese maritime expansion.

Prime Minister Scott Morrison said Monday that the base will be located on the country’s east coast. Along with supporting Australia’s “new nuclear-powered submarines” and creating more “deployment opportunities in” the Indian and Pacific oceans, the base will allow “regular visits” from U.S. and U.K. nuclear submarines, according to a press release from Morrison’s office.
