ONE Nation Senator Pauline Hanson has prompted a walkout in the Senate with her maiden speech that said Australia risks being “swamped" by Muslims.

“We are in danger of being swamped by Muslims who bear a culture and ideology incompatible with our own,” she said.

The Queensland Senator also paid tribute to her infamous maiden speech in the House of Representatives 20 years ago in which she said Australia was in danger of being swamped by Asians.

Only now, she claims Islam represents a threat to Australia’s way of life and called for borders to be closed to immigrants — even offering to drive people to the airport to leave the country permanently.

“If you are not prepared to become Australian and give our country your undivided loyalty … I suggest you go back to where you came from,” she said.

Greens Senators walked out of the chamber in protest following that remark.

Opening with “I’m back, but not alone,” she rehashed the anti-multiculturalism rhetoric of her first in 1996.

“It’s about belonging, respect and commitment to fight for Australia,” she said.

“Australia had a national identity before federation and it had nothing to do with diversity and everything to do with belonging.”

The woman who once married and had two children with a Polish immigrant said the Australian way of life had suffered, thanks to residents born abroad.

“Indiscriminate and aggressive multiculturalism have caused crime to escalate and social cohesion to decline,” she said.

“Too many of us live in fear of terrorism.

“Muslims are prominent in organised crime, anti-social behaviour is rampant and ... surveys find that in neighbourhoods of Muslim settlement ... Australians, in general, are more fearful.

“Islam cannot have a significant presence in Australia if we are to live in an open, secular and cohesive society.

“We have seen the destruction it is causing around the world. We will be treated as second class citizens with second class rights if we continue with the, ‘She’ll be right mate’ attitude.”

Ms Hanson also took aim at welfare recipients, foreign investors and the legal system, calling for a ban on immigration and to look out for the “aged, sick and helpless first.”

With a shaking voice, Ms Hanson opened by idealising the controversial parliamentary speech of 20 years ago.

“It was speech that shook a nation woke up many Australians and gave hope to those who thought no-one was listening,” she said. “That speech is still relevant now.”

The Queensland senator even described herself as a “political prisoner”, in reference to a jail stint for electoral fraud on what she described as “trumped up charges”.

In reference to her three One Nation colleagues in the Senate she said: “I cannot begin to express the pride and honour in being joined in this place by three of my colleagues.

“As a strong, united team, I guarantee we will make a difference.”

The “simplistic” speech was seen by commentators as a “flick-the-switch answer to complex issues.”

Greens leader Richard Di Natale said his party’s senators walked out because they have an “obligation to call out racism wherever it occurs.”

“Racism has no place in Parliament but that is what we have just heard from Senator Hanson. I stand by those people hurt by her words,” he tweeted.

Fellow One Nation Senator Malcolm Roberts said he agreed with Senator Hanson that Islam was not “compatible” with Australian way of life.

“Islam is not compatible with our society, our country, our laws,” he said.

Ms Hanson also warned that globalisation, free trade and ethnic diversity have “seen the country’s decline”. She called for a ban on burkas, Muslim immigration and Australian companies paying for Halal certification.

“Halal certification tax has been forced on us, costing Australians $10 million a year ... it’s a money making racket,” she said.

She also placed Islamic schools and mothers on welfare on notice, saying they should only receive payments for one child and not more.

“If they have more there will be no increase to the welfare payment get a job and start taking responsibility for your own actions,” she said.

She took aim at Family Law, as she did in her first maiden speech, and claimed women make “frivolous claims” and that unless there were changes “we will continue to see murders out of sheer frustration”.

Earlier, she had insisted an eye-roll during a speech by Senator Roberts was not out of disrespect but because she was “simply embarrassed.”

“I wasn’t rolling my eyes out of disrespect to Malcolm’s kind words, I was simply embarrassed.

“After 20 years of having most people in the public eye slander and take pot shots, I guess I don’t take compliments too well.”
