>Just say they are not paying taxes and getting our money abroad etc.

This is said pretty regularly in the media in Australia, and honestly no one cares. Even big mining companies like BHP pay little corporate tax on shore, and after years of it being 'exposed', honestly the general public don't seem to care.

I think it's more accurate to say the public cares somewhat, and consequently politicians do too (they sometimes roll out accusations of "un-Australian" tax minimization to suit their agenda). But politicians don't dare to move against the big companies because they know they'll lose. Both in campaign/party donations and in being targeted at the next election if their policies are going to impact those companies (see what happened with the mining companies and the Carbon tax). This same thing could happen with these "internet" companies who would only need to devote a little of their local advertising to a campaign against the change and against the party proposing it to have any public support cancelled out and politicians quickly reversing their position.
