The perceived contradiction can act as a clue that leads the reader to an ironic interpretation. The purpose of the text was by no means to mislead anyone into thinking it was a genuine job ad, rather, placing itself in the role of the state that offers jobs in the form of a job ad serves as a means of ironic concealment, which enables indirect criticism to be presented. It's about polyphonicity, which is realized both by usurping another type of text and by using multiple roles.
In the end result, both the state Australian B2C Email List offers jobs and the ironic writer's own, critical voice can be heard at the same time. Imitating a job advertisement not only enables this kind of playing with roles, but also expands the targets of irony in such a way that the job advertisement itself as a type of text becomes the target of parody.
Why be ironic? Recognizing irony requires knowledge of the topic at hand, the people involved, the roles prevailing in the situation, and the expectations connected to them and the situation itself. To be genuine, irony must always be consciously intended by its user, even though the final interpretation is dependent on the recipient and is created - if it is to be created - in their consciousness as a sum of many factors. By studying the contexts in which irony is used, things about our language and culture will be revealed.
