请问有没有童鞋知道ebay上怎么付款？

you can register a free paypal account  online and then transfer some $$ from your australian bank account to your paypal account.  Once you have paypal set up you can pay ebay and use many other online shoppings.

many ebay sellers also accept direct bank deposit, you can contact the seller to negotiate payment method.
