On 2 April, Rau was visited by Iris Indorato, the honorary consul for Germany and France in Cairns. Rau communicated with her in German, because officials did not know at the time that Rau could speak English, and it was presumed that she was a lost German citizen. Indorato said that her command of the language was fluent but "child-like" in terms of vocabulary, and that Rau could not remember basic information such as her parents' names, and where she had been born.
