Our total export revenue in AUD for 2019 was $273 billion USD ($384 billion AUD) *

If we process 20% of #1 & #2 here in SEZs, then we would double # 1 & #2 in export revenue IE: add an extra $236 billion AUD.

Simarily we can also process at least 20% of our gold & gems and double its value (add $25 billion AUD to to export revenue.

All other things being equal this would lift our trade surplus over $260 billion a year

Our food exports are a slightly different kettle of fish, IMO, but there is nothing stopping us from processing and packaging our oats
and wheat ready for global supermarket shelves like what other countries do with their speciality cereals. Just have a look at Wiilies
, Coles & Aldi shelves and you'll see packaged food from all over the world on our shelves like pasta (wheat) from Italy, Noodles (rice )
from Asia etc. Even NZ is doing a better job with agribusiness than we are!
