Automatically load a currency other than default

Hi guys,

First time poster long time lurker.

I have the default currency on my site set as USD & would like to keep it this way as this is the currency my supplier uses. The site currently loads in USD & is viewable in AUD only if you click the A$ under currency. If possible, I would like the site to load in AUD & have the option to be viewed USD.
Does anyone know if this is possible?

I am using 1.5.1.2

very nice and clean
You can force AUD
1. EDIT: index.php

2. FIND: 3. AFTER, ADD:

Worked like a charm, thanks!

Qphoria Can you help me ? I can't change currency on my web site index. currency has'nt change When I changed it index.
Please help me and Look it: alisverisbook.(c)(o)(m)

I find this solution fixes the currency. If one is using say five currencies for checkout pupose, then by this solution, one cannot change the currency.

Is there a way by which (even though the initial display currency is AUD), one can change the currency to any other as one wishes from the frontend options?

thanks
