One Nation has won its first federal Lower House seat at the ballot box in a historic result breaking the Coalition’s 77-year hold on the NSW seat of Farrer.

The populist party’s David Farley defeated fellow frontrunner Michelle Milthorpe and Coalition candidates Raissa Butkowski and Brad Robertson to clinch the seat, commanding a double-digit lead within two hours of polls closing.

“This is not only a win for Farrer, it’s a win for the rest of Australia,” One Nation Pauline Hanson said after victory was declared.

Earlier she said it would be “a win for our nation”.

“We are going to work hard now for this electorate and our nation.”

She said voters “realised that we are the last hope of changing things in this country”

“People have fear for the future generations, no hope of owning their own home, you know? And the cost of living is just destroying families,” she said.

Shortly after, Mr Farley claimed victory.

“We’re like a mason with a chisel and a hammer, and we’re carving letters into the Australian democracy,” Mr Farley told supporters at the official watch party in Albury.

Flanked by Senator Hanson and soon-to-be lower house colleague Barnaby Joyce, Mr Farley said the party “has reached the end of its beginning”.

“We’re going through the ceiling,” he said, calling the win his “biggest achievement” and the “most euphoric experience” he has had.

He went on to name water, health and immigration as his other key concerns.

“We’re not going to implode any of our industries that are reliant on good quality, assimilating migrants into the country,” he said.

“But we’re not going to entertain people to come here and live off our balance sheet, our purse and give us nothing.”

Mr Farley vowed to focus on cost-of-living, saying his first order of business was “this damn net zero crap”.

“It’s not what Australia wants and it’s not what Australia needs,” he said.

“We’ve got to have a policy that first Australia, not the world.”

Commenting on his fellow candidates, Mr Farley said “they fought well” but questioned if they fought cleanly.

‘We are where we are’

Ms Milthorpe was teary eyed as she addressed her supporters to concede defeat.

The long-time teacher and advocate for child sexual abuse survivors has now failed twice to win Farrer but drawn hefty support from across the political spectrum in both attempts.

She questioned whether Mr Farley was what the electorate needed but cut herself off, saying: “We are where we are.”

After thanking her closest supporters, Ms Milthorpe implored voters across the country to not “let this energy dissipate”.

“Keep having conversations with friends, family and colleagues,” she said.

“Keep hoping for a better future for our beautiful children, and keep fighting, and I will fight right alongside of you.”

‘Voters never get it wrong’: Ley breaks silence

Farrer’s former longtime MP Sussan Ley urged the party she used to lead to “accept this result with humility”.

Ms Ley held the seat for 25 years and quit after being rolled as Liberal Party leader earlier this year.

She hastily left federal politics after her ousting and has kept out of the public eye, despite pumping $250,000 into the Liberal candidate’s campaign.

“The seat of Farrer was created in 1949. Until tonight, at every one of the 30 elections since, through different and challenging circumstances, it has been held without exception by the Liberal and National parties,” Ms Ley said in a statement.

“It would be an error to reduce both the scale and significance of tonight’s defeat to a Coalition split which occurred months ago, or to misattribute it to the date the vote was held.

“I urge the Liberal leadership to accept this result with humility because the voters never get it wrong.

“On the day the leadership spilled in February, the new leader said the Liberal Party needed to ‘change or die’.

“Three months later, the result in Farrer demonstrates that statement to be far truer today than it ever was then.”

‘Western Sydney, here we come’

Mr Joyce earlier warned Anthony Albanese his party was setting its eyes on Western Sydney.

Labor has dominated Sydney’s multicultural, working class western suburbs for decades.

Asked post-election call what his message for the Prime Minister was, Mr Joyce said: “Western Sydney, here we come. Believe you me.”

He said he had come across One Nation supporters backgrounds while campaigning in Farrer.

“We’re coming to Western Sydney,” Mr Joyce said.

“I look forward to meeting you there, Chris Bowen. I’ll be on the stage. Come talk to me.”

New One Nation MP

Mr Farley will join Mr Joyce in the lower house, following the former deputy prime minister’s switch from the Nationals to One Nation late last year.

Mr Farley is a high-profile agribusiness leader and who served as chief executive of the Australian Agricultural Company, as well as and managing director of Australian cotton giant Colly Cotton.

A heavyweight in the irrigation and commodities sectors, he has worked across the world, including in the US.

With just 12 per cent of ballots officially tallied, Mr Farley surged to 41 per cent of the primary vote to his independent rival’s 28 per cent.

The Liberal and Nationals candidates were sitting just north of 9 per cent.
