Hi Jtaylor007,
Welcome to the AGL Community!
Unfortunately we do not offer EFT as a form of payment. You can find all of the payment options available to you here. If you're having issues with our website and app overseas, then I encourage you to use BPAY or PayPal if possible.
Kind regards,
Jayden
Or perhaps AGL can fix their website. I am in the same position overseas and I'm completely unable to pay my bill because the "Pay now" link is broken. Judging by the date of the original post, it isn't a new issue. Foolish of me to simply return the next day as if it were a temporary outage.
