Double Cross-Border Fees?

[osasko]

My Bank Account is in GBP

My paypal button charges in  US$.

My question:

Say someone from Australia for example buys a product:

The conversion would be AUS - US$ - GBP when I withdraw.

Paypal charges 2.5% extra for crossborder . So AUS to US$  = 2,5% 

Then US$ to GBP Bank Account withdrawal =1% for charge to receive payments from another country.

Will there be another 2.5% charge for currency conversion from Paypal?

If they don't I guess my bank will charge another conversion fee.....

Total charges:

2.9% + $0.30

+2,5%

+1%

+ Charge to convert from US$ to GBP

Sounds like almost 7-10% of the value of the sale.......

Am I understanding these fees correct?

The cross border fee is an additional 1% . 2.9% +1% + 30 cents.

Now there is a currency conversion fee if the buyer does not pay in your currency. 

All you have to do is set it in your Paypal preference.

This page says there is an additional 2.5% as well.

There is 2 currency conversions here

Aus to USD (Paypal Account)

and

USD to GBP (To withdraw)

So just trying to figure out the total cost it will take to actually get "cash in hand"
