As this just isn't the usual tweak to interest rates, and may impact those that use their account where the balance doesn't always increase, worth noting the new change ubank just announced on their website.
I know for me that makes ubank unsuitable and now need to find an alternative for daily banking over the new couple months.

From 1 October 2025 (so there’s nothing for you to do now)
We’re evolving the way you qualify for bonus interest on your Save accounts. From 1 October 2025, you’ll need to grow your combined balance across all your Save accounts (excluding linked offsets and excluding any interest credits) by $1 each month.
I think leave it in ubank until the new requirement comes into play at 4.6%, towards end of September start moving it to Macquarie at the 4.85% rate for 4 months before it goes back to 4.5% in the fifth month.
