787 S/O courses planned December and every month to the end of the FY.
Of course crew retirements may keep things ticking along beyond that albeit at a lower rate and more aeroplane orders will see things going at a fair clip.
Personally I reckon that QF are short of airframes and won’t be able to cover the planned flying when the 744s go in just over 12 months time. I reckon at least 4 more 787s are needed to cover that or keep the 744s longer. Who knows though. Probably aren’t are any firm plans either way yet.
