Just a heads up, HK is 919.8MHz...
Thanks for pointing that out. 
I should have been more precise in my wording. My understanding is that the AU/NZ/HK version of the Almond+ comes with both the 919.82 MHz frequency (for HK) and the 921.42 MHz frequency (for AU/NZ). I'm located in Australia, so am really after the latter frequency. 
Let me know if I'm mistaken.
