Labor has gained three notional seats and lost one in NSW, as part of the Australian Electoral Commission's federal redistribution.

The commission announced its final decision on boundary changes to a number of federal electorates on Thursday, keeping most of the changes proposed by a committee including the Electoral Commissioner and the NSW Surveyor-General last year.

ABC election expert Antony Green said that the changes meant Labor gained three notional seats in Barton, Dobell and Patterson.

Shadow minister for transport and infrastructure Anthony Albanese's seat of Grayndler will gain the Sydenham area, which was previously recommended to go to the seat of Barton.
