One Nation leader Pauline Hanson made her entrance into parliament on Wednesday evening by proclaiming Australia was in "danger of being swamped by Muslims".

"Now we are in danger of being swamped by Muslims, who bear a culture and ideology that is incompatible with our own," she said.

Ms Hanson accused Muslims as being more violent. "Multiple social surveys find that neighbourhoods of Muslim settlement are suffering from collapsing social cohesion and fear of crime," she went on to say.

"Not only is terrorism seen around the world but it is now part of our society with Muslim refugees involved in the Lindt Cafe siege, the Curtis Cheng murder in Sydney and the stabbing of the two police officers in Melbourne."

It was rhetoric that prompted the Greens party to leave halfway through, its leader, Richard Di Natale describing it as "vile" and racism.

Together, our MPs have left Senator Pauline Hanson’s 1st speech because we’ll call out racism wherever it occurs, including Parliament. — Richard Di Natale (@RichardDiNatale) September 14, 2016

An international study called the the Global Religious Futures project, compiled in 2015 by Pew Research Center from the latest data (2010), has determined the percentage of each major religion across 234 countries around the world - and Muslims make up just 2.4 per cent of the Australian population.

The religions were Christianity, Islam, Hinduism, Buddhism, Judaism, the religiously unaffiliated and the 'other religion' category, which includes Sikhs, Shintoists and Taoists. It also looked at folk religions, which it defined as Aboriginal and African traditional religions.

SBS analysed the religious makeups in the 35 countries that constitute the Organisation for Economic Co-operation and Development (OECD), an intergovernmental economic organisation formed to build the global economy and trade.

It found that Turkey had the greatest percentage of Muslims at 98 per cent, followed by Israel at 18.6 per cent, France at 7.5 per cent, the Netherlands 6 per cent and then Belgium (5.9), Germany (5.8), Austria (5.4), Greece (5.3), Switzerland (4.9) and in 10th place, Sweden at 4.6 per cent.

Australia ranks 16th at 2.4 per cent, with Hinduism noted as the fastest growing religion.
