TO WIN MAJORITY GOVERNMENT

* Labor needs to gain 21 seats on a uniform swing of 4.3 per cent from the 2103 election. On paper, it has three of those seats (Dobell, Paterson and Barton) in the bag following a redistribution of NSW electoral boundaries, but loses the abolished seat of Hunter.

* The coalition can afford to lose 14 of the seats it holds now on a swing to Labor of 3 per cent.

* The latest round of opinion polls has the parties 50-50 - a swing to Labor of 3.5 per cent but not quite enough to win government.
