5 months in Sydney.

Hello, I am going to work and live in Sydney for 5 months from may till september. I come from the Netherlands and i am not familiar with bouldering in this city.  I was wondering what the best spots are in Sydney or close to the city. I won't have a car so driving far is not realy an option.  Also i hope there is some one who would like to boulder together or maybe could guide me here. Thanks!
