Personally, I've had quite a good run in 2022 booking and flying premium seats on Qantas Points. I've probably spent nearly 500k points this year on various flights, including;
- QF J A330 SYD-PER return (April)
- QF J SYD-SIN return (Feb)
- MH J SYD-xKUL-SIN return (June)
- QF J MEL-HBA (Sept)
- QF J SYD-HND return (Nov)
- QF Y -> J Upgrade SYD-CNS (Feb, as a Bronze)
- QF Y -> J Upgrade BNE-SYD (April, as a Silver)
- QF J SYD-xMEL-LAX (Nov)
- QF F LAX-SYD (Dec, Platinum Release)
- AA Y LAX-YVR return (Nov, cash prices were very high, thanksgiving)
and forward bookings I have
- QF J HND-SYD (Mar)
- JL J SYD-HND (Feb)
- CI J SYD-TPE return (May)
Of all of these, only one was a Platinum release and only 3 QF flights were booked while I was a Gold/Platinum, which may have allowed me to access extra inventory.
This is probably why I've been so successful too though. I'm happy to bring up the award calendar (accessed with multi-city search), spot a J seat, then begin planning a brand new trip around that. In the first half of the year, I was (ab)using Fly Flexible to make speculative bookings based on when I thought Singapore / Japan / Western Australia would open up. I think all of my flights were booked less than 6 months in advance.
With that said, I think about 1/3 of these flights have required intervention on my side due to schedule changes, which has admittedly become a lot easier after achieving Platinum status, since the call center has been a lot more helpful.
I think there's no need to be too gloomy. Well, if you have a million points and you want to spend them quickly then I can see that being an issue, but if you have 100~400k points and you just want to book a single Business Class holiday, I think it's still pretty doable. Of course, you're not going to be able to get to Japan in the next few months on points (have you seen the cash prices on those tickets?), but if you have a reasonably sized list of destinations and dates to travel, you should be able to find something.
With this said, it's definitely true it's slightly easier to get flights out of Australia on SQ Krisflyer than Qantas. I don't even think this is a case of SQ releasing more award space than Qantas though, it's simply the much lower number of people in Australia with access to and redeeming KF points compared on QFF points. I bet if there were as many KF credit cards, sign up bonuses, and accounts in Australia as there are QFF, then the availability would be the same or worse. Of course, this fact doesn't help you as a Qantas customer, but I'm inclined to believe Qantas isn't even being thaaat stingy with their award space compared to other carriers.
On the topic of the value of Qantas points vs. e.g. AS miles or even Krisflyer, I completely agree in terms of the raw value per point. However from an Australian perspective I still continue to collect QFF points because they're so much easier to collect than other miles. I can easily get 100k+ QFF points from a card sign up, whereas that's not really possible with Krisflyer (except for the current Citi card, but that's a rare deal). Therefore, the amount of flights I can redeem from one Credit Card churn is more or less the same between Qantas and Krisflyer, even if the absolute number of points required is higher.
