Logitech MX Keys Advanced Illuminated Wireless Keyboard.
Cheapest it has been for a while since COVID has hit (RRP $199) if you have prime and don't mind the different keyboard layout.
NOTE****: This is the US International Layout QWERTY (920-009415). This would differ from AU keyboards (920-009418) as the enter key is larger and the "| \" key is in a different position.
If you are lucky you could get Officeworks/JB Hifi to price match and get a local one.
Is this mechanical?
