Pauline Hanson's bad week isn't over, with newly released video showing the One Nation leader questioning the official story of the Port Arthur massacre.
Australia promptly changed its gun laws following the 1996 atrocity, in which a mentally disturbed man armed with a semi-automatic rifle murdered 35 people in the Tasmanian town of Port Arthur.
In footage shot by al-Jazeera, Hanson and her chief of staff James Ashby can be heard discussing the massacre.
"An MP said it would actually take a massacre in Tasmania to change the gun laws in Australia," she told al-Jazeera's Rodger Muller.
"Haven't you heard that? Have a look at it. It was said on the floor of parliament... I've read a lot and I've read the book on it, Port Arthur. I read a book on it, on Port Arthur. A lot of questions there."

Muller had been posing as the leader of a fake gun rights group as part of a three-year investigation into the far-right party.
But the One Nation leadership didn't stop there.
"That whole September 11 thing, too," Ashby said, questioning the official narrative of the September 11, 2001 attacks in the US which left almost 3000 dead.
Hanson has declined to comment publicly on the latest video from al-Jazeera, as she's reportedly been bitten by a tick leaving her face "unrecognisable".
"She's waiting until the final episode airs and her face goes down," a One Nation source told news.com.au.
Earlier this week al-Jazeera released footage of Ashby and One Nation official Steve Dickson seeking funding and assistance from the United States' powerful NRA gun lobby group, hoping the money would help them secure more seats in parliament - in exchange for weakening Australia's gun laws.
Hanson called the report a "hit piece" and said she'd refer al-Jazeera to the Australian Security Intelligence Organisation.
"A Qatari government organisation should not be targeting Australian political parties," she wrote on Twitter.
The Australian Electoral Commission has already said One Nation didn't break the law because the solicitation happened in Washington DC, outside of its jurisdiction.
The One Nation pair said they'd been "on the sauce" for several hours before the al-Jazeera sting. Australian Prime Minister Scott Morrison said that was "no excuse".
"There are many reasons not to vote for One Nation. It's a long list," he said.
The revelations about One Nation's efforts to weaken Australian gun laws comes less than two weeks after a gunman opened fire in two Christchurch mosques, killing 50, and prompting a crackdown on weapons here in New Zealand.
