Ability to set a currency as default

Currently, I have to continuously have to reset the currency to AUD when I'm updating a new product. When I'm doing a whole new catalog of items, it gets tedious. Is there a way to set the default currency (especially for the non-international girlies or guys) so we can keep it to AUD, and if we want to change it to add in the others we can. It defaults to USD for me.
