Brisbane was among the world's major cities where forces of flying Cybermen emerged led by Missy. Taking to the skies, they created a cloud of cyber-pollen above the city. These pollen clouds would then rain upon the graves, recruiting the dead of the Earth into a new Cyberman army. When control of the Cyberman army went to the hands of the recently-converted Danny Pink, he ordered all Cybermen to return to the skies and self-destruct, taking the pollen clouds with them in their combined explosions.
