USA

The exchange rate fluctuates with both yours and the Australian economies. As an American, Brit or EU citizen traveling to Australia you usually come out well ahead. You can check the current exchange rates at: www.iccfx.com

The safe answer is NO. Australia operates on 220-240 volts. However, you should check your device for allowed voltages -- some devices may be "dual voltage", allowing a wider range from 100-240V.

You can purchase voltage converters and adaptors fairly cheaply from electrical stores such as Radio Shack prior to leaving for Australia.

It's really not too bad; we normally fly QANTAS and they are very good! On the vast majority of flights to Australia every seat has its own TV personally controlled by you. One of the best ways to pass time is to watch some current movies, documentaries (normally about Australia) or play video games. The food is surprisingly good on these long flights and the service is exceptional.
