On 29 April, a DIMIA officer contacted the Missing Persons Unit of the Queensland Police, and sent them the information they had collected about Anna. The Unit said that they had no records matching the descriptions provided. On 11 May, Rau asked if she could apply for a German passport, and DIMIA officials prepared a form filled in with her details, giving her name as Anna Schmidt. Four days later, the German Consulate in Sydney rejected the passport application, because it contained insufficient or inadequate information. On 17 June, DIMIA contacted the Australian Embassy in Berlin for assistance in identifying Rau.
