No Need in knowing when BFTS dates will be. Can take along time to get accepted after flight screening and then you need to do 4 to 5 months of initial officer training and then BFTS. When I went through it was 6 months from Flight Screening to next RAAF intake then 6 weeks inbetween OTS and BFTS then 6 months before 2FTS.
Navy follow same syllabus as RAAF till Wings at 2FTS. Don't think you are going to get a copy of the actual syllabus, worry about that when you need to.
