I have heard that there is an "official" exchange rate in Argentina and a street rate which is much higher because currently, the locals are finding it really hard to get foreign currency.
When I travel I usually just withdraw money from an ATM. Does that mean that in this case, I should be bringing lots of USD to exchange?
Does it have to be USD? Do they accept Australian dollars at all?
I also heard it is technically illegal to do this, do I need to take any precautions?
