One Nation officials caught talking about receiving $20 million from the American gun lobby claim they were drunk and set up by a Middle Eastern spy.

Queensland leader Steve Dickson and Pauline Hanson's chief of staff James Ashby were sprung meeting with pro-gun groups including the powerful National Rifle Association.

In footage from Al Jazeera, Mr Dickson is recorded as saying that with enough funding, One Nation would get the balance of power and have control over the government, to be able to weaken Australia's gun laws.

Prime Minister Scott Morrison lashed out at One Nation for considering selling off Australia's gun laws.

"No law should be up to the highest bidder as some part of foreign interference," he told reporters.

"But the fact that they were prepared to do it, if you were ever wondering why you shouldn't be voting One Nation there's a pretty good reason."

Mr Ashby said they only spoke with undercover Al Jazeera reporter Rodger Muller about the potential $20 million in donations .

"We'd arrived in America, we got on the sauce, we'd had a few drinks and that's where those discussions took place, not with any potential donors, no one but Rodger Muller, Steve Dickson and myself," he told reporters.

Mr Muller posed as the head of fake lobby group Guns Rights Australia, which was set up by Al Jazeera, and initiated the One Nation meetings with the NRA.

"We would win potentially the balance of power if we win two seats in the lower house," Mr Ashby said in the hidden camera video.

"I reckon we could do that with two million dollars.

"If you had 20 (million dollars) you would own the lower house and the upper house."

Mr Ashby and Mr Dickson believed they were speaking to a gun lobbyist.

Mr Dickson and Mr Ashby were in Washington DC to meet with members of the National Rifle Association (NRA).

"If we could get that sort of money, imagine, we could change Australia," Mr Dickson said.

"You'd have the whole government by the balls."

After being caught in the secret video sting, Mr Dickson said that Australian authorities should enact foreign interference laws to investigate Al Jazeera.

Mr Dickson said the comments had been "taken out of context" and came after a long night of drinking alcohol.

"It was employed by a Middle Eastern country, Al Jazeera, to come to Australia as a spy to infiltrate into Australian politics," he told reporters yesterday.

His comments came after Mr Morrison slammed One Nation for their involvement in seeking the foreign funding boost.

"Where we have reports that One Nation officials basically sought to sell Australia's gun laws to the highest bidders to a foreign buyer and I find that abhorrent," he said.

"When John Howard put those laws in under a Coalition Government, they were put in to protect Australians."

Mr Morrison refused to say whether One Nation would be placed last on Liberal how-to-vote cards in the upcoming federal election.

"I'm not interested in getting One Nation's preferences. I'm interested in getting their primary vote," he said.

Mr Ashby and Mr Dickson's comments were made before tighter regulations on political donations were enacted in January.

"No law should be up to the highest bidder as some part of foreign interference and it's our Government that has actually put in place the laws that would make that impossible, at least it would make it unlawful in this country to do that," Mr Morrison said.

"If you're ever wondering why you shouldn't be voting One Nation, there's a pretty good reason."

Mr Morrison said he separated One Nation voters with the party members themselves.

"Our gun laws that John Howard put in place under a Liberal National Government have been keeping Australians safe for decades and how dare they seek to trade those for money and votes from a foreign buyer," he said.

"That's not on. I won't put up with it."

In a statement issued yesterday morning, One Nation did not dispute the way they were presented in Al Jazeera's story.

But they did call on the media outlet to be investigated.

"Al Jazeera are a state-owned propaganda arm of the Qatari government that supports Islamic extremist groups and are not a legitimate media organisation," the statement read.

"It is understood One Nation were targeted because of its strong approach to reducing immigration numbers and a travel ban on countries with terrorism links."

Their statement declared they "have always complied with the law".

One Nation has long supported loosening gun regulations in Australia.

A statement from Labor frontbenchers Mark Dreyfus and Clare O'Neil tied the One Nation news to the Coalition's preferences in the upcoming election.

"Today’s shocking revelations that One Nation have courted US gun-rights lobby the National Rifle Association to help achieve their aim of watering down Australia’s world-leading gun laws are yet more reason – if one were needed – to put One Nation last," the two said.
