Award flight on JQ morning service Ballina - SYD

[vertisol]

I'm trying to book an award flight SYD - BNK return and would prefer to come back on the 0910 service from Ballina rather than the afternoon service. No matter what dates I try there doesn't appear to be any award seats on that flight.

Just seems a bit strange to me as I can book the afternoon service any day through November.

Does anyone have any insight into this?
