Australia, like many countries around the world, has people who seek to enter unexpectedly without a valid visa. It is the responsibility of the nurse working with unexpected arrivals to learn more about their client. Two main issues are needed to briefly address. Firstly, the discursive categorization of people who arrive unexpectedly and secondly, some considerations that nurses need to think about when working with this vulnerable group of people. Nurses should ensure that a system has been developed that links the nurse to other health and human service professionals. Detailed treatment and management plans must be established and education and training needs to be provided for all relevant personnel.
