It is a balanced programme (at least 3 periods) but I am not sure if this will let you get the full marks on the "balanced programme" criteria. Sculthorpe is an Australian composer, isn't he?
If a candidate can play his choices convincingly, that's fine and actually most important! Last year, my friend played Mozart, Chopin and Ravel for her AT. In fact, I recently found out that some one played only 2 pieces in his LT (Beethoven Tempest and Barber Excursions), and he got 80 marks. I had also heard someone played an all Liszt programme for his LT.
I am not sure if you want to play 2 Bach followed by 2 Brahms and finally Schulthorpe, or Bach, Brahms, Bach, Brahms, Schulthorpe, or other combinations. It is not necessarily for the candidate to play in sequence of "period".
For whichever French suite you will pick, I suggest you double check the playing time (as you know, long repeats are discouraged).
In this part of the world, candidates usually play pieces from 4 composers (baroque, classical, romantic, impressionalist/20th century).
I played Bach, Mozart, Brahms, Debussy, Rachmaninoff and Szymanowski in my AT 4.5 years ago

Good luck!
