No technical reasons, but lots of political ones. In particular, spectrum licensing regulations.
Even if you could put up a compelling safety case you'd still end up with a protracted court battle against the likes of Telstra, who paid several billion dollars for their spectrum and sure as hell aren't going to let anyone else use it, even if they're not using it themselves.
A couple of years ago Cisco showed off a VoIP gateway which spoke CDMA on one side and Ethernet on the other. The idea was that when you were in range of its CDMA radio your traditional mobile phone would "roam" to the VoIP cell and you'd get to use your mobile to make calls through the office phone system (or someone else's VoIP phone system -- whatever).
Such products are destined to be complete failures in Australia, because the spectrum they use is locked up by the telco incumbents.
