​This publication assesses the political impact of the final electoral boundaries for NSW released on Thursday 26 August 2021.

This publication does not provide predictions for the 2023 election. The estimated margins provided are best thought of as possible results of the 2019 election had the election been fought on the new boundaries. The estimates cannot take account of the difference in candidate and campaign effort that would have occurred had the 2019 election had been fought on the new boundaries. The difficulty of splitting polling place catchment areas to match new electoral boundaries, as well as allocating declaration votes to new electorates, means the estimated margins in this publication should be treated as approximations.

All estimates have been calculated based on the actual results of the 2019 election published by the NSW Electoral Commission, and with reference to enrolment transfers and maps published by the Electoral Districts Redistribution Panel. However, responsibility for all calculations, and the assumption underlying them, must rest with the author.
