Thanks Kumar.
I know I'm not the only one in Australia with this issue. I did some research on it before ordering, but didn't consider that the functionality was limited to US only.
Totally with you on this one Byron, I purchased yesterday from JB HI FI after see all the adds for the "Spartspeaker" I have been using my Alexa for timer's routines and Hue Lights so was really looking forward to replacing it with this speaker. I have a perfectly good working Amazon Echo at home now so why its not working with the Sonos is beyond me. The Google Assistant better come through as a simple firmware update. So I take it no one still has a workaround ?
