Where's all the UA J (Polaris) TPAC availability gone?

[MathNerd]

UA used to consistently release J availability for their TPAC routes MEL/SYD/BNE <-> LAX/SFO/IAH, sometimes at T-1 and all the way up to T-30 even.

Now, when running any sort of search (Example 1 or Example 2), there's nothing (at least in J).

Has a "change" happened? I have been monitoring the LAX/SFO <-> MEL route recently, as I need to book a flight home after a trip to the US in about 2 months time.
I'm a fair way away from their usual T-14 (I think?) drop, but if what I'm seeing right now is the usual, then it'll be a bit tough to get the date/s I'm after when that window does roll around.

Any advice or insight into what's going on?
Thanks!

That's the risk with last minute availability. It may not show up.

It's happened several times before.

Damn. There's basically 2 options available, from where I sit:

1. Wait, wait and cross fingers that anything opens up (open to any West Coast US/CA, to any East Coast AU - that's the long haul, and happy with Y to reposition at either end).
2. Use the AmEx Statement Credit "Spend $1000 or More at United Airlines, Get $400 Back" on multiple cards to "load up" my United account (at a ~40% discount) with Travel Bank or Future Flight Credits, then use these to book the flight. The offer ends at the end of this month.

I've just never ever seen a lack of availability, for the entire time I've monitored this route/s. Just so happens that the availability drops off just when I need it to continue its pattern. It's all part of the game, I guess

Thanks for your insights, very much appreciated!
