How Much Is The New Moon And Eclipse Novel Of Stephenie Meyer Sold In Australia?

I am not from a speakinh English country so I can’t find New Moon and Eclipse novel in English. I am really looking forward to reading them because they haven’t been translated into my own language yet. I’m having a trip to Australia this June so it could be a great opportunity for me to buy them. Do you have any idea of the price of them in Australia? Please let me know so that I can prepare enough money to afford them.
