I don’t know about the payment of the Australians but in Europe I paid 13 euros a month, and in the U.S. i think they demand 13$ (which is less than 13e damn)
well that’s all i had to offer.
As far as monthly payment is concerned, I’ve been playing FFXI for nearly 3 years now so I still pay in US dollars, the monthly fees adding up to about $16.95 US a month total ($12.95 USD monthly subscription, plus two extra characters for a $1 USD a month Tetra Master subscription), which usually equates to around $18-20 AUD a month, depending on the current exchange rate.
From what I understand though, new players who have the European version of the game now cannot select US dollars for payment and can only pay in Euro dollars or British pounds, depending on whether they live in the UK or other PAL territories (when I first registered with PlayOnline back in 2005 US dollars was the only payment type avaliable).
Incidentally, I have a friend who has the X-box 360 version of FFXI and can only pay in Euros – there was no option to select US dollars when he registered. So I guess SE has restricted being able to select a certain currency for payment depending on what region your copy of the game is from.
