Here's an alternative to the Dell/Xiaomi, I personally got this monitor and tested it this week and think it's worth the current sale price. The usual price is $639.
You can get a free Kogan First trial (I was eligible again despite just using it a few months ago, don't know why) to get the $579 price. Shipping to QLD was $19.99 for me.
Important Activate the Kogan First trial outside, manually, DON'T DO IT IN THE CART DURING CHECKOUT. This allows you to use gift card/store credits.
Can get a further 6% off gift card through Suncorp Rewards, which is instant and available for anyone with a free online debit account.
Mini review
Exceeded my expectations, the 165 Hz is real. At the UFO blur test, there's SIGNIFICANTLY less smearing than the Dell S2722DGM which is also a 165 Hz VA panel. Factory calibration is also pretty good. Comes with a very premium-feeling all-metal stand (only tilt, no height/swivel), and is vesa-compatible. Has a 2-port USB "hub", and included cables are also quite high quality (-feeling, I don't have testers).
Didn't touch any of the "HDR" stuff - I know it's going to be underwhelming. (so is everything else at this price and ~400 nits peak brightness)
NOTE: The curvature is actually 1800R, not the advertised 1000R. I compared it with my existing 34" 1800R, and it was identical. I was hoping for a more aggressive curvature, but unfortunately the options at these specs and price point are all 1800R.
My personal calibration profiles (not a professional).
my Kogan limit is $10
