One Nation has announced it hopes to field a "strong, local candidate" in Gilmore at the federal election.
State leader Mark Latham said the party was motivated by Scott Morrison's announcement that the Liberal Party would preference One Nation below Labor.
"We'd very much like to have a candidate in Gilmore to get in the field, in light of Scott Morrison's decision to preference Labor," he told the South Coast Register on Friday, April 29.
"We're talking to people now and hopefully in the next week or two will have someone lined up."
Mr Latham also took aim at Liberal candidate for Gilmore, Warren Mundine.
"Warren Mundine is a sham candidate - he was shoehorned in over the democratically selected candidate," he said.
"We want a strong local who can expose him for what he is."
Mr Mundine said he was not surprised by the possibility of another candidate - or Mr Latham's comments about his legitimacy.
"I wouldn't be surprised if we have a cast of thousands for this because Ann Sudmalis is retiring at this election, and when there's a vacant seat, opportunists come out of the woodwork," he said.
"As the Prime Minister has announced, we will preference the Nationals, because they are our coalition partners, and One Nation will be preferenced below Labor.
"I'm not surprised by his comments, because we've had argy-bargy over the last couple of days in regard to his DNA policy. It's insane and a bizarre situation. Welfare should be based on need alone.
"He's irrelevant to me, I'm about the people of Gilmore and we'll see what happens on election."
Nationals candidate Katrina Hodgkinson echoed Mr Mundine's sentiments about the number of candidates running for Gilmore.
She said she opposed any party attempting to wind back Australia's gun control laws.
"I don't support any diminution of our gun laws," she said.
"We have worked to get that policy right, and I think we have. It's not necessary to have high-powered weapons in urban areas."
She said that the National Party had not yet determined their preferences beyond the Coalition.
Independent candidate Grant Schultz, and Labor candidate Fiona Phillips both denounced the One Nation Party's position on gun control legislation.
"I'm not going to preference anyone who seeks to weaken our gun laws," Mr Shultz said.
"I don't want to see American-style gun laws. It's crazy. It isn't going to happen."
Ms Phillips said she wasn't concerned about a last-minute candidate.
"I'll absolutely be placing them last, I think they're the most divisive party around," she said.
"As far as I know, none of the other candidates - except perhaps the Greens - who have said they'll preference them last."
