Australian Bird Question

To whom it may concern. Hi my name is John and I was wondering if you would be able to answer a quick question for me. I am trying to find out the names, or a list of the following birds. I am doing some personal research and this may go part way to helping me. What I am specifically after is the names and types of the following 1) High flying birds of Australia. 2) Preferably white in colour. Or a similar shade to this. 3) Their diet. 4) Flight speed and manoeuvrability. 5) Height of sustained flight. 6) Length in time of sustained flight at high altitude. 7) Whether they are predator or prey. Your help would be greatly appreciated. Thanking you very much, John
