Two-party vote count

Hunter had become somewhat marginal in the 1980s when much of its territory was shifted to the newly created Charlton. Since 1990, Labor has never tallied less than 53 percent of the two-party-preferred vote. Labor's worst two-party-preferred vote was 52.4% in 1984 and best result when challenged by an opposing centre-right candidate was 80.6% in 1961.

Hunter is one of Labor's only regional seats in New South Wales, likely due to it being a blue collar electorate. However, the Nationals and One Nation have increased their support over time due to Labor's policies on coal mining, a large industry in the region. However, the Labor MPs that represent Hunter often come from the Labor Right faction and support the Coalition's policies on coal mining, which more conservative than Labor's.

First-preference vote count

Labor's worst first-preference vote was in 2019, when the current member won only 37.5% of the primary vote; the previous 100-year worst being 44.5% in 2013, again by the incumbent member. Labor's best primary vote was a thumping 76.9% in 1946. As of 2019, the Division of Hunter is considered a marginal seat.

2015 proposed abolition

In 2015 the Australian Electoral Commission announced plans to abolish the federation seat of Hunter. Due to changing populations, overall, New South Wales was to lose a seat while Western Australia was to gain an extra seat. Electors in the north of Hunter were to join New England. The roughly 40 percent remainder were to become part of Paterson, with the Liberal margin calculated to be notionally reduced from 9.8 percent to just 0.5 percent as a result. Since the Commission's guidelines require it to preserve the names of original electorates where possible, the commission proposed renaming Charlton to Hunter.^[3][4][5][6] Effectively, this meant that Charlton was abolished, and Hunter pushed slightly eastward to absorb much of Charlton's former territory.^[7][8] Most voters of the new Hunter came from the former Charlton. However, Charlton's Labor incumbent, Pat Conroy, brokered a factional deal to contest neighbouring Shortland in order to allow Fitzgibbon to continue to represent the new Hunter.
