When you arrive in Sydney you'll want to meet other people. There are many ways to do this. You can meet people in your line of work, with similar interests or with the same background.
A very good place to start your Sydney exploration and gather information is the Newcomers Network. The Newcomers Network is an online guide for people who have moved or are planning to move to Australia, Sydney in particular. It provides resources from government, non-government and private organizations which can be accessed free of charge or registration. They also organise monthly 'Welcome to Sydney' events and have up to 100 people attending.
