When does award seats get released for Qantas and Finnair on the Qantas website?

I am trying to book economy reward flights from Helsinki to Perth via Singapore for around 7th Jan 2025, however, the reward seats for the direct legs are only available up to the end of Nov. I can get reward JQ seats or stopovers in Tokyo in early Dec, but late Dec/early Jan hasn’t seemed to open up yet for the direct routes?

I’m looking to secure economy seats for flights AY131 (Hel-Sing) and QF72 (Sing-Perth).

Will January reward seat dates slowly open up or am I missing something? I read somewhere Qantas now just dumps a whole bunch of dates open and then announces it, or is it still 355 etc before flight date that seats open?
