Qantas reward seat availability via BA/Avios

Hi all,

Anyone know if Qantas only releases reward seats to partners at short notice? I’ve been looking for flights MEL/SYD-NZ in January and there is effectively no available seats with the exception of some rare 787 flights from SYD-AKL.

Seems unusual this far out especially with how many flights they operate to AKL/WLG on narrow bodies, and on investigation there are plenty of available seats over the next couple of weeks.

Cheers
