For what it is worth the milk powders they refer to doesn't come from Australia. Also the price of the milk powder (given its good quality and source) is reflective in the quarterly report under COGS. A bit more research will tell you where it comes from, so percentage aussie made? Sub-10%.at best.
It has some work to do before it shows any form as a viable company to be ASX listed as the peak price just after listing was a long way up from where the share price is right now and the quarterly does show any material signs of kicking goals in the near-term. Even the listing price was on the point of being edgy for a low asset base business that can vapourise overnight.
A high percentage of aussie-chinese retail investor on the share register at a guess.
