buying an E-11....

[Nerf]

There generally isn't a problem with getting the Hasbro toys into Australia. Target used to sell them in store but they are 'very' rare to find. Someone here may part with one if you ask around but eBay would be your best bet to find a reasonably priced one.

As Duras mentioned, you can either do the Hasbro conversion, pipe build or full resin kit. Most of us here use the conversion or pipe builds.
