A controversial all-Queensland, all-white episode of ABC's Q&A descended into a shouting match on Monday night as panellists, including Pauline Hanson and Bob Katter, noisily debated issues ranging from climate change to the White Australia policy - with Ms Hanson admitting she didn’t know what the term "final solution" meant when a Katter MP used it in Parliament.
In a throwback to the origins of Hansonism, the phrase "please explain" - Ms Hanson’s famous 1997 answer when asked if she was "xenophobic" - was used twice during the show.
It first arose in a question from a Muslim audience member to Mr Katter, an independent MP, about the recent speech by his party senator Fraser Anning in which Senator Anning used the term "final solution".
In his controversial speech, Anning said "the final solution to the immigration problem is a popular vote", later denying that he purposefully invoked the term used by the Nazi regime to describe a genocidal policy of exterminating Jewish people.
Mr Katter: "If you can find anywhere in that speech where [he] advocated White Australia policy I'd be very curious to find out where it is."
Host Tony Jones: "Bob, if you want to know I'll let you know."
Mr Katter: "Go right ahead.
Mr Jones: "Fraser Anning's speech was all about the White Australia policy. He said it was a bipartisan policy for a solely European-based immigration, supported by Labor leaders. He was talking about the White Australia policy."
Mr Katter: "Tony, he said a preponderance of Europeans. If you want to be technical, it means a majority."
Then Senator Hanson entered the debate, admitting that even though she had condemned Senator Anning’s speech, she had no idea what the term meant when she heard it.
"I'm not going back to 'final solution'. I had no idea what it meant to tell you the truth. That was a ‘please explain’ moment... I will say that I was appalled by him referring to White Australia policy. We're past that. They tried to tag me with that years ago, that I was wanting a White Australia policy."
The Greens’ Larissa Waters: "I wonder why."
Senator Hanson: "There’s no wonder why, Larissa. I never said that. I called for equality. If you look at my immigration policy it is non-discriminatory. It's people like you and the media that have misrepresented what I've tried to say over the years. I would not be associated with it because I've never called for it. Never, ever."
Both Mr Katter and Senator Hanson affirmed their support for a "people’s vote" on immigration levels.
The far North Queensland panel, broadcast from Mackay, also debated climate change, electricity prices, the culling of crocodiles, the banking royal commission and the division of Queensland into two states. The Adani mine controversy also inspired fiery debate.
