Sydney, Australia

Sydney was, during the Twentieth Century, the largest city in Australia. Even by 2047, the city had largely remained pristine, due to a massive wall surrounding the city and protecting it from the harsh Yellow Zone outside.

Sydney was also the GDI HQ for the Australia-New Zealand Theatre of War, serving to counter the Nod HQ at Ayers Rock. A clash between the major GDI and Nod forces in the region would seem inevitable.

However, before GDI and Nod could start battling, the Scrin Arrived. The first encounter in the A-NZ theatre was when a band of Elite Nod troops came under attack by the scrin, shortly after hijacking GDI nuclear warheads.

Kilian Qatar, acting commander-in-chief of Nod decided to join forces with the GDI in the area to turn back the invaders at Sydney. However, she also had an ulterior motive; to steal the nuclear launch codes for the stolen warheads from GDI.

The Scrin attacked Sydney, and both GDI and Nod forces attempted to hold the line. The city walls were breached, and Nod managed to sneak a saboteur in close enough to a tech center to steal the codes. Apparently, GDI believed the nuclear warheads stolen in the Outback were lost, or they would've tightened their defenses. During the battle mysterious transmissions from an unknown source ordered Nod forces to attack GDI positions as well.

Later, despite a successful holding action at the city walls, the Scrin managed to establish a foothold in Downtown Sydney, by the docks. Nod covered GDI's forces as they were being airlifted to safety. However, to the astonishment of the Nod forces, Kane contacted them, revealing himself to be alive. He immediately ordered the destruction of GDI forces in Sydney, authorizing the commander to use the stolen nuclear missiles.

Nod successfully destroyed the GDI positions, and most of Sydney, with the missiles.
