Am I right in saying that a UK (PAL) Wii U will run Australian games? 

Are their any power considerations I have to take into account (As in terms of a voltage transformer - Had some problems with a US 3DS with this). I have basic UK adapters so it shouldn't be a problem but do I need to get a transformer?

Will i have problems with eShop and online connectivity. Can I set up a UK account and use an Ozzie credit card, or can I set up an Aussie Account on the UK Wii U.

Club Nintendo. Will UK Wii U games be compatible with my Australian Club Nintendo account. Can I register the Wii U on my account or do I have to set up a new account for UK

Cheers for any responses, looking forward to my Wii U
