$104 Billion of Aus finished/semi finished products at a $3000 FOB amounts to 34.6 million tons of finished semi/finished products or 9500 tons/day or 396 tons /hour. ....that's 8 x B Doubles!
Even if we do quarter of that (99 ton/Hr) that would be a big start, IMO.
Again IMO, this can be done without the Government owning the enterprises...just providing SEZ with the appropriate infrastructure and services (like what China does!)
