Nintendo has announced that the Nintendo Switch is hitting stores March 3. It's a global launch.
With this tweet from Nintendo Australia, we're assuming Australia will be part of that launch.

The price? We're not sure at this point. But the US$299 price point translates roughly to $400, so it wouldn't be out of the realms of possibility to expect a $399.95 price tag.
But as always, expect the unexpected. It might be a little more, it might a little less. We've contacted Nintendo locally and will update when we hear back.
