After Oceania Union condemned Earth Alliance's invasion of South America, and voiced their their support of PLANT, Earth Alliance declared war on the Union as well. Although the Alliance's attention was mostly occupied by ZAFT, they eventually sent a fleet to subdue the Oceania Union. Set to arrive at early April.
Meanwhile, on April 2nd, using the chaos in communication and energy wrought by the deployment of N-jammers, ZAFT once again dropped its forces from orbit to destroyed the invading Alliance fleet, and securing the Gulf of Carpentaria on Northern Australia.
Once the site is secured, ZAFT orbital dropped per-fabriacted building modules down to Australia, and began the construction of their first stronghold on Earth; the Carpentaria base.
Core structures of Carpentaria base base built in just 48 hours, from there ZAFT continued to expand and complete the remaining construction.
