Same here in Australia. I actually think we have developed the technology (and the matching legislation) that allows pole mounted cameras to detect this while driving at 110kmh down the expressway. I know many people that have been "busted" and even though I use a handsfree holder, just placing (when you forgot to do so before you drive off) is just as illegal here.

I did laugh when of course sometimes they would pickup someone holding a chocolate bar while driving. While not necessarily the best thing to do with the one hand, not illegal all the same.
