Update: Not exactly sure what is going on but there appears to be some sort of data breach with cheapgames.com.au atm. Do not use just yet. They have an issue that is resulting in some customers private information being revealed publicly.
Nintendo New 3DS [White] – £108.47 delivered
Australian version, but the hardware is identical to the UK version. You’ll get to get a charger though.
I have imported plenty of stuff from Australia in the past and never been charged any additional fees. Your millage may vary.
I encountered a bug where selecting to deliver to the same address as my billing address wouldn’t work, but if you opt to ship to a different address and just enter the same address again it would work fine.

This turned up for me in the UK today, no customs charges. Excellent service.
