Mr Fang won the 18^th out of 21 seats after about three weeks of vote counting and preference calculation ended on Monday afternoon, with the final four MPs declared.

Mr Fang, who will continue as upper house deputy whip told The Daily Advertiser that he would "hold to account" minor parties for their election promises in the Riverina and western NSW.

"I absolutely see it as part of my role to ensure I keep those people to account who have made promises to the electorate that I don't think were ever going to be delivered," he said.

"We have seen people make promises such as the delivery of the Griffith hospital in two years, such as the (Visiting Medical Officer) vacancies being immediately filled in Leeton.

"People made promises in this election that they knew they would never be able to fulfill and I will hold them to account."

Mr Fang said he also saw his job as "looking after the south-west".

"As nice as (Wagga MP) Joe McGirr is,he doesn't have a voice in government so I will have to work with Joe to make sure Wagga moves forward," Mr Fang said.

"We need that voice in government, particularly for those western areas that have elected Shooters (Fishers and Farmers Party)."

The re-elected NSW Coalition government has its own list of promises to act on, many dating back to the by-election campaign in September, including the Tumut hospital upgrade and parking for Wagga Base Hospital.

"We are a government that honours its commitments and there is an iron-clad guarantee that construction at the Tumut Hospital will begin by the end of the year," Mr Fang said.

Mr Fang entered Parliament in August 2017 following the retirement of Duncan Gay.

"When I was in parliament last time is was through a casual vacancy, and even though you are elected by the party this is the first time through a direct election that have have been in parliament," Mr Fang said.

"We expected that I would be elected, that's the way we were looking at the projections, but you never really know until you know.

"(Liberal Democrats former federal Senator) David Leyonhjelm called that he had been elected early on and then it turned out that he unfortunately wasn't, so projections can be wrong."

Mr Fang will be broadly representing an area of NSW that has seen a continual political upheaval, with the the Nationals finding themselves in a lower house minority in the west and south-west of the state.

Independent Wagga MP Joe McGirr will serve his first full term in the lower house after backing up his byelection win on preferences with a comprehensive primary vote victory last month.

Nationals Cootamundra MP Steph Cooke also backed up her byelection win and the Liberals hold Albury but the Shooters, Farmers and Fishers Party expanded from Orange to take Murray and Barwon.

Mr Fang said he was confident in being able to work with the minor parties who were also elected.

"We are going to need five votes to pass any legislation, but I think for the most part there will be a real collaborative approach and the legislation we bring forward will be for the betterment of NSW," he said.

"If people wish to act as roadblocks, it will be for political reasons only and not that they have the best interests of NSW at heart.

"We will work with everyone in this parliament and it's going to be exciting."
