Australian Quarantine Naval Clash (Project Noah)

The 2017 Australian Quarantine Naval Clash was a series of unprovoked skirmishes between the U.S. Navy and the Royal Australian Navy during the quarantine.

A U.S. Navy guided-missile destroyer attempted to seek safe harbor in Australia after one of its compartments was compromised with the Infected. Australia was already under quarantine and work together alongside New Zealand in trying to deal with infected boat people coming from Indonesia. Despite the naval blockade, some of these refugees eventually made their way to Australia. The destroyer insisted on getting past the blockade so it fired its harpoon anti-ship missiles on the Australian ships, sinking three before it was sunk by both the Royal Australian Navy and the Royal New Zealand Navy. However, a MH-60 Seahawk was able to fly from the sinking destroyer where it crashed in Australia as one of the personnel in it was infected. From there, cases of the Zombie Fish Worm multiplied rapidly in the country.

It was the first time the ANZUS allies fought, though war was never formally declared due to the breakdown of communications.
