I did my initial interview last Tuesday, 3rd of April. All applicants who were there had less than 250 hrs except 1 (no it's not me). The closest person had 120 hrs but still only had PPL. So, they do still accept applicants with less than 250. Also, it would not hurt if you go and READ their website. They WILL ask you things like "Where will you be doing your training? How long will it take? What aircrafts will you be flying? What course will you be taking over there? Will you be doing any SIM there in Adelaide?" Which are ALL in there. *below*

best of luck to all applicants!
