You will need plug adaptors, but you can find out online which one(s) to get.
I haven't been there since 2005, and in that short period of time so much has changed. We didn't have i-pads or kindles or need power strips. I'm sure that most places you stay at will have hair dryers somewhere, either in the bathroom or tucked away in a desk drawer or something like that. And I think there's a special outlet in the bathroom for electric shavers.
From the description, you'll be staying mostly at Rydges hotels. They're a major chain in that part of the world. I have stayed at some, but not the ones on the list.
