The game is available, but it still has a downside.
Wii Party U, which was recently revealed to not be receiving a digital version on the Nintendo eShop in North America and Europe, is available on the eShop in Australia. The game is being sold for the full price of $79.95, which is the same price for the physical version of the game that comes bundled with a Wii Remote Plus controller.
