The seat of Warringah would expand westward from its current border of Spofforth Street in Mosman, to take in Cremorne, Neutral Bay, Cammeray, Crows Nest, Kirribilli, Waverton, Wollstonecraft and all of the North Sydney business and residential district.
Bennelong would be reshaped with one of the biggest expansions by adding Hunters Hill, Lane Cove, Woolwich, Greenwich, Longueville and parts of Chatswood that are west of the Pacific Highway and south of Fullers Road.
In a more modest change, Mackellar would expand on its southern border to add Killarney Heights, take in all of Forestville and add North Curl Curl.
On the northern edge of Sydney, the seat of Berowra would expand slightly to take in all of North Epping and Epping, previously in Bennelong. The border of Berowra would also shift eastward from the Pacific Highway to take in all of Hornsby, Waitara and Asquith. The seat is regarded as very safe Liberal territory and is held by Julian Leeser.

One of the key seats for the election, the marginal electorate of Parramatta, would expand slightly to take in areas previously in surrounding electorates.
Held by Labor MP Andrew Charlton, the seat would add Girraween to the west and Ermington to the east. It would also gain the constituents who live between Epping and Carlingford, west of Midson Road.
On the southern side of the harbour, the changes mean the seat of Banks, which is held by Liberal frontbencher David Coleman, expands to include parts of Milperra and Punchbowl, potentially shifting the balance in favour of Labor.
At the same time, however, the seat will also add waterside suburbs such as Carrs Park and Kyle Bay.
The seat of Hughes, held by Jenny Ware for the Liberals and previously held by outspoken former Liberal Craig Kelly, expands westward to include Ingleburn, Macquarie Fields and Glenfield. These areas are currently part of the Labor electorate of Werriwa.
