Hey, I've got good news. I grew my own quinoa With all the worries about the farmers in Bolivia and Peru who couldn't get quinoa, I decided to grow my own. And it worked It is easy to thresh, but the only problem is that it looks like goosefoot, a weed. But I have to tell that I live in a cool climate where you can grow many Andean crops (the Netherlands) so perhaps for the most people in Australia it wont work. Greetings Matis
I don't know how the climate is where you live but other people from Oregon also grew quinoa. I am buying a southern Chile quinoa which is more adapted to my region. I buy it from a site in Oregon too https://adaptiveseeds.com/product/quinoa-dave-407 This year I just grew the quinoa from a health food shop but I think that this species is better.
