Oh I get the business model alright, of that there is no doubt. What you don't seem to grasp as its actuality. TB8 was a case in point that has some correlation to AU8 on a number of fronts.
You are interesting as you firstly said "...AU8 is earning foreign money rather than domestic $!!" and now you are saying "The company IS earning money from overseas people (whether they are tourists or via their daigous) u do not understand their business model??? $A into AU8 tills !!! Having inflow of foreign money is surely better for the economy." Make up your mind.
Supplemented by foreign milk because Australia doesn't produce enough? Good gawd where do you get your data from, besides the small fact that many appear to think it is aussie milk powder.
I would offer you are not on top of the business model at all and lest it be presented to you you would still struggle to get it.
It might be a small time punter short trades on the pips and if that is your game then best of luck but dont think it is or will be much else in its current form. A market capitalisation of ~$80m is way too high for a company like this but it tugs at the heart strings of retail punters and maybe you are on, of many. Then the best of luck with whatever you sink in to it.
