[LINK] Google's WiFi bungle

IANAL and I always use the term "broadcast" in the simple technical  
sense, not in the legal sense so you would have to read my emails in  
that light.

I assume when you use the term "authorised" and "unauthorised" you are  
using that in some legal sense.  Which act does it come from?  ACMA is  
mostly concerned with spectrum use and transmitter power.  I'm not  
familiar with the broadcasting act but I can't imagine it is relevant  
to wifi.  There is an act dealing with wifi?
