At the end of the day, I still come back to local product (Perth Mint).
I do know there are other manufacturers out there, PAMP, Geiger and others - and they do a superb job at producing world class products.
However - if I need to trade out of my position in a hurry, I want to have the widest possible buying audience, and with products stamped and made here, there is potentially less hesitation in buyers who may not be as familiar as we all are with the products that exist, and what fakes look like and so forth.
