Miscellaneous: Because I travel often I purchased a converter and an adaptor kit which includes all the adaptors I would need for any particular country. If you forget to take your own adopter, most hotels will "loan" you one (at a charge, which they will deduct once you return it). If you travel often, I would recommend that you purchase your own and take it with you on your trips.
Miscellaneous: Get a plug adaptor. Australian plugs are damn strange looking things. Well, they are to me ;-) But anyway, the point is that I found it quite difficult to get an adaptor in Sydney, although I eventually tracked one down in a hardware store in George Street. Cross it off your list early on ...
