Hey joanaw!
I was just reading your post. Have you been invited to the assessment day? If you are from Sydney, I would recommend that you attend an open day, as you do not require an invitation to attend an open day. It will save you a rather expensive airfare! You can apply for an open day online, however it is not essential. You can hand in your resume on the day without applying...this is what I did! Emirates will be in Melbourne in September, and Perth and Brisbane in August.
Best of luck, if you need any help...i'm happy to help out!
