I will be traveling for the U.S. to Australia for about two weeks. I would like to have a cell phone or calling card to be able to call my family in the U.S. Since I do not travel often, I only want something temporary. Do people have recommendations? Should I get a disposable cell phone? An international calling card? One advantage of a cell phone is that it has internet but I'm not sure if disposable phones have them.

Maybe the above are not the only options and somebody else has even better suggestions.

Thanks for your advice.
