What are the sports and outdoor activities?

 Because the Northern Suburbs is not a clearly defined region, the Northern Suburbs may also include suburbs in the Upper North Shore, Lower North Shore, and the Northern Beaches. 
 Do you know anything about its regions? 
 What can you tell me about Sydney?
