As soon as the stage 5 zombie was killed, the behaviour of the zombie horde that were still fiercely attacking before, quickly returned to normal as sounds could easily distract them, allowing Alex's team to divide and conquer all these zombies.
Alex and the other 8 people quickly ran back and regrouped with their other fighters that were still trying to catch up to them. The group then swiftly went back towards Sydney City to check the situation over there. After they ran through the Australian wilderness for 1 hour, they reached the defensive line of the Sydney Gate, where they could see the area was still swarming with zombies.
