In theory yes, but in reality the Australian-owned megacorps are all owned by a single person, and every single one of the media outlets they control endlessly pushes the political message of just one side.

So although they're "Australian owned", they're very far from good "neutral" sources of information.

EDIT: For those wondering, it's like virtually all of Australia's media being run by Rush Limbaugh. And he has a cozy relationship with the government, so all of this is just a way to force Google and FB to pay him more money.
