We live in Adelaide, is it possible to pay by Master Card as I don't have a Debit Card.

We are travelling to China in January 2014 after meeting up with my sister in Hong Kong. My sister will buy bus tickets for us to go for a few days. We don't know which hotel to stay until we get there. Can we still apply for it and what document do we need to support our applications as we would like to get them done soon in Australia? Also, we live in Adelaide and can we pay by Credit Card if Postal application is the only option? Thanks
