I received a message this evening from Adobe informing me that my monthly Photoshop subscription has jumped from $A14.29/month (~$US9.45) to $A23.99/month (~$US15.87).
Whilst $23.99/month is not going to send me broke, a 68% increase is still a pretty steep price hike. 
I understood from Adobe that the yearly cost (payment in advance) will not change. But perhaps only valid in the Netherlands:
"Starting January 15, 2025, the price of the Adobe Creative Cloud Photography plan with 20 GB of storage will increase in all countries.
Annual membership, billed monthly: $5 increase, from $9.99 to $14.99 per month.
Annual membership, prepaid: No increase, price remains $119.88 per year."
In addition: "The Creative Cloud Photography plan (20 GB) will be discontinued on January 15, 2025, and is no longer available to new subscribers. However, Adobe will continue to offer existing plans until users decide to cancel. "
