It doesn't matter what the governments say what bitcoin is. Bitcoin is what it is and it can't be changed, it is a decentralized cryptocurrency in Australia, Japan , USA etc
Yeah, those governments can say anything what they want, totally true. And it is a good news for Australian then, which its government admit bitcoin as money. For Japan, maybe thats because of Mt.Gox incident.
We can ignore what government say about bitcoin, because we will using it, no matter what they say. But their statement could affect people's mind who dont have any idea about bitcoin before, so it will make them to stay away from bitcoin.
