Using AUD rather than USD and Paypal

My store is set up in Australia.

Switch To Default Language Currency is set to false.

I had set up products for say $10.

My Currencies default to AUD. I selected update currencies when I did this.

I have checked the products and they show the sales value as $10.

In the store, the products seem to be showing for $9.60 which I can see is the USD conversion value in my currencies section.

Clicking on to purchase through PayPal which I have set to AUD, it correctly shows the $10.00 in PayPal.

Somehow my store is displaying the products in USD and I cannot see how to change this.

How to I make sure that my store appears to the customer in AUD?

Answered my own problem. Not sure if it is the only way, but ... changed my english.php file ...

define('LANGUAGE_CURRENCY', 'AUD');

And then switched the Switch To Default Language Currency to true.

Seems to be OK now.
