Is there a "safety case" or "risk analysis"... would be interesting to see and who it was conducted by. A significant factor would also be use of English (?) by the students.
There would have to be one done for the airport as they have received government funding. If you remember what a saga the Gold Coast ILS was and that was needed and on a into wind runway!! You could try and get YMIA paperwork through Freedom of Information but I don't know what the criteria is for that to be released. I don't think English proficiency is so much an issue for IFR training as there will always be an instructor in the aircraft for that.
