Was able to get a english / australian (non-spanish) version of logitech mx key from officeoworks with a price match from ple computers for $141.55. Not the best but not bad.

Can provide a pm if you really need the receipt but committed requests only ?:)
OK, I found Logitech MX Keys listed on OzBargain 6 times since 21/11, or almost once a day.
I think any OzB punter that wants an MX Keys would have got one by now.
