Hello,
Very disappointing to hear such news. Seems pretty unprofessional by a company such as Emirates. Details like this should be made very clear to the public before the open day takes place.
Emirates have got a website to apply through and leave your resume on, including photos. It comes across to me as a complete waste of time to come to Australia and recieve all these cv's and choose a group to interview out of these resumes'. This could have been done in Dubai and then invitations could have been sent to the successful applicants who could of prepared themselves in a propper way.
Keep your heads up guys, they will be back soon!
Andrew!
