It has a unique history, swinging back and forth between independents and the Nationals for more than half a century.

That trend goes back even further to the 1940s, if you include the long-standing MP Bill Chaffey, who swung from an independent representative to the Country Party and back again during his 33-year reign. After Mr Chaffey retired as an independent in 1973, the seat was regained by the Nationals through Noel Park, who held the seat for 13 years.

Enter the independent juggernaut Tony Windsor, who wrestled the seat off the Nationals in 1991. After a decade as the Tamworth MP, Mr Windsor resigned to contest the federal seat of New England. The subsequent 2001 Tamworth by-election was won by National Party candidate John Cull, who defeated Tamworth mayor James Treloar, an independent endorsed by Mr Windsor.

However, Mr Cull's reign was short-lived, losing the 2003 election to independent candidate Peter Draper, who secured a narrow 2.5 per cent margin. Mr Draper won re-election in 2007 and almost doubled his margin.

In 2011, the seat again swapped hands, with Mr Draper losing to Nationals candidate and current MP Kevin Anderson with a 12.5 per cent swing. Mr Anderson was re-elected in 2015, again beating Mr Draper.

This year, Mr Anderson will have to fend off challenges from independent Mark Rodda, a popular Tamworth councillor, and Shooters, Fishers and Farmers candidate Jeff Bacon, who has been campaigning since mid-2018.

Cr Rodda has a large profile within the Tamworth LGA, and got the most votes of any councillor in the last local government election.

Mr Bacon has run a relentless campaign, with many of his key election issues forcing a election promise funding response from Mr Anderson, including a $10m upgrade of Werris Creek Road and a $53m upgrade of Gunnedah hospital.

Labor has traditionally struggled to get a foothold in the electorate, however candidate Stephen Mears said people were more open to the party's message this year.

The largest electorate in the state, covering almost half of NSW and 13 local government areas, including the towns of Boggabri, Baan Baan, Wee Waa and Narrabri.

Barwon is usually considered a Nationals stronghold, with the party holding the seat since 1950.

However, incumbent Nationals MP Kevin Humphries is stepping down, and the Shooters, Fishers and Farmers Party have used his retirement as an opportunity to go after the seat hard.

SFF candidate Roy Butler has run a strong campaign, with a big focus on the impact of drought and the government's response, and is considered a good chance of toppling the Nationals.

Mr Butler still has a monumental task ahead of him, given Nationals candidate Andrew Schier will benefit from the 12.9 per cent majority his party holds.

All of the Liverpool Plains, excluding the area around Werris Creek, is located with the Upper Hunter, including Quirindi, Wallabadah, Willow Tree, Spring Ridge and Caroona.

The seat has been represented by the Nationals/Country Party since the 1930s.

In 2015, Mr Johnsen attracted 38.9 per cent of the first preference vote, ahead of Labor's 32.5 per cent. On a two party preferred basis, the Nationals hold a slim 2.2 per cent majority. The Upper Hunter saw more than a 20 per cent swing against the Nationals in 2015.
