Hi Cortez,
I just received an email from Grain & Grape in Yarraville, Melbourne and they are happy to order in the Wyeast Sake #9 for me although like NNL it will take a few weeks to get in.
I have got some Kome-Koji sitting in my freezer at the moment. Two of the three major Japanese supermarkets here in Melbourne stocked it. The one that didn't stock it told me that it was impossible to import here so don't believe that line if you get told it.
I ended up getting it from Fujimart here in Melbourne, it was roughly $6 for 200gms, so I needed two packs to make Vision Brewing's basic recipe (have you seen the Vision site?). It was in the freezer and in square blocks the same shape as the 2 minute noodles you get from the supermarket. The front had a see-thru panel.
I believe that Fujimart have a store in NSW too, but it's called Tokyomart instead. I just asked for 'koji' and they instantly knew what I was talking about.

My first batch turned out sour so next time I'm going to make a half batch while I am experimenting. I think the main problem was I should have fermented it at a much lower temperature, probably low teens. I don't have a spare fridge to use and it's been really hot here lately. Next time I'm going to use a stainless stock pot and put that in an esky surrounded by ice to make about 3 litres. I used champagne yeast, at around room temp here 22 deg.. It also has a champagne taste to it, so I'd steer clear of that yeast again.

After a few dud batches he is having success with a high gravity trappist ale yeast I think.
One final thing you may be also interested in.. I've been researching how to make Japanese clone beers and found out about rice malt syrup. You can get it in Coles in the health food section at about $4 for 500gms and I picked some up last night. Apparantly it's marketed as a honey substitute for vegans. Although I'm going to use it for the beer, I'm wondering if it could be used in place of (or in addition to) the Kome-Koji when making sake. Something to ponder...
Good luck with your search, and be sure to let me know how you get on!
Cheers,
