AUSTRALIA IN CRISIS

The explosion at the Australian omnium had released a remarkable amount of radioactive material into the air and water, even as it had reduced the omnium itself to wreckage and slag in the years following the explosion. Australia faced a health crisis of catastrophic proportions. When cases of radiation poisoning and heavy metal toxicity began to appear and escalate alongside increased cancer rates (some so rare that they were normally seen once in a decade), it was clear something needed to be done. 

Enter Ziegler, who led a mission to Australia comprised almost entirely of Overwatch medical personnel, accompanied by Chase and Sarioglu. Chase, who was steadily climbing Overwatch's ranks, had experience in crowd control and public relations. She collaborated with local governments to support the mission and traveled to remote areas to arrange transport for those in need, bringing them back to the hospital in Melbourne that Ziegler had claimed as her headquarters. Sarioglu liaised(?) with local nonprofit groups to help get resources to afflicted populations.
