Yes, it sounds interesting, but getting it in AUS is neither easy or inexpensive. (only one distributor listed for AUS, and it's pre-order only)

It can be purchased through eBay US, but with shipping and GST, it works out to roughly $63AU for 236ml (8 oz.). And that's just for the grain filler. If you go with their 3-step process, it adds up quickly.
