Looks like a good price for one of the newer Asus AX models.
*Amazon support can't confirm if it comes with AUS power plug or firmware but if it doesn't and your not comfortable with that you can have it returned for free.
Currently $499 at JB Hi Fi & Bing Lee
Interesting note from review:
"More on the chosen hardware, this new AX82U is unique, being the first platform I've had in my hands to use the 6750 SoC from Broadcom. When paired with the BCM43684, both radios in this solution are Wi-Fi 6e capable, making it possible ASUS could push a firmware update later in the year to enable the 6GHz band support."
