Great book. I found it really easy to use. I like how you can jump from different sections depending on what you want to do in the city. It makes it as easy as flicking through a paperback.
There's lots of great info in here, lots of local information. I haven't been to Sydney before so I liked that the book goes through ways of doing touristy things, that would usually cost quite a bit if you didn't know any better. I have bought a "to do for free" type book in the past and it was just full of lists of parks to sit in. Not exactly my idea of 'local info'! I'm glad to have read from somebody who has done it well.
The book also gives advice on going out in Sydney, markets, travel, etc.. basically just honest, local info. Also, there's lots of links to websites and free apps to check out. I recommend this book to anyone going to Sydney. Thumbs up!
