Sydney's metropolitan area is a vibrant mosaic of regions, organized by the Greater Sydney Commission into three "cities" and five distinct districts, encompassing 33 local government areas (LGAs). This framework includes Eastern Harbour City, Central River City, and Western Parkland City, which collectively reflect the city's diversity. The Australian Bureau of Statistics further extends Greater Sydney to include the Central Coast region, adding approximately 330,000 residents to the area.

### Inner Suburbs
The Sydney Central Business District (CBD) is a historical hub stretching about 3 km south from Sydney Cove, flanked by Farm Cove and Darling Harbour. Surrounded by notable inner suburbs such as Woolloomooloo, Surry Hills, and Pyrmont, the CBD features narrow streets that echo its convict origins. Key areas include transport hubs at Central and Circular Quay, cultural sites in Chinatown, and shopping at the historic Strand Arcade and Westfield Sydney. Gentrification trends have transformed neighborhoods like Pyrmont into high-density living spaces, while Green Square undergoes an $8 billion urban renewal project.

### Inner West
The Inner West, encompassing the Inner West Council and municipalities of Burwood, Strathfield, and Canada Bay, stretches about 11 km from the CBD. Historically, this area was home to the colony's elites, but it has evolved into a desirable residential locale known for its vibrant village centers. The Inner West boasts cultural enclaves such as "Little Italy" in Leichhardt and "Little Korea" in Strathfield, along with major shopping destinations. This region is well-connected via multiple transport options, including railway lines and ferries.

### Eastern Suburbs
The Eastern Suburbs, including Woollahra and Randwick, are among the most affluent areas in Australia. Streets like Wolseley Road in Point Piper rank among the world's priciest, contributing to a demographic characterized by significant wealth and privilege. Key attractions include Bondi Beach, Randwick Racecourse, and extensive shopping facilities at Westfield Bondi Junction. Recent infrastructure projects, such as the CBD and South East Light Rail, aim to improve connectivity for residents.

### Southern Sydney
Southern Sydney features suburbs like Kurnell and Cronulla, rich in historical significance and natural beauty. Kurnell marks the landing site of James Cook in 1770, while Cronulla is renowned for its beaches and proximity to Royal National Park. This district also includes Hurstville, a commercial center for the southern suburbs, reflecting a blend of urban and suburban lifestyles.

### Northern Sydney
Northern Sydney encompasses the Upper and Lower North Shore, along with the Northern Beaches, known for their scenic beauty and recreational offerings. Major commercial hubs include North Sydney and Chatswood, with educational institutions like Macquarie University enriching the region. The Northern Beaches, including iconic Manly, remain popular holiday destinations.

### Hills District and Western Suburbs
The Hills District comprises hilly suburbs in north-western Sydney, while the greater western suburbs, including Parramatta and Bankstown, represent some of Sydney's most multicultural areas. Parramatta, often regarded as Sydney's "second CBD," serves as a significant business and cultural center. The western region is characterized by its historical landmarks, such as Old Government House in Parramatta and the abundant green spaces of Sydney Olympic Park.

Together, these regions create a dynamic and multifaceted portrait of Sydney, reflecting its historical depth, cultural richness, and ongoing evolution as one of Australia’s premier cities.
