The year is ending with Labor polling particularly strongly at the state level down the east coast, new data from Essential Research shows.

In NSW, the once-mighty Baird government led Labor on a two-party preferred basis 51%-49% in the October-December quarter, with the Coalition on 43% -- down a point from the July-September quarter -- and Labor up one to 38%, while the Greens remain on 9%. That's based on a sample of nearly 3500. In December, Labor ends the year 50-50 with the Coalition, reflecting a Coalition primary vote lead of just three points over Labor.
