One Nation leader Pauline Hanson used a landmark address to argue Australia’s immigration program has pushed the nation into a state of crisis, while calling for an end to multiculturalism and a return to what she described as a ‘monocultural’ society.

Speaking on Wednesday, Senator Hanson claimed Australia’s immigration intake over recent years had fundamentally changed the country’s social fabric and raised concerns about national identity, social cohesion and population growth.

‘A total of more than 1.9 million people arrived in Australia from mid-2022 to mid-2025,’ Hanson said.

‘Undeniably, immigration, or immigration policy, has our country in a state of crisis.’

At the centre of that crisis, Hanson argued, was Australia’s multiculturalism policy.

‘We cannot be a multicultural society. We are a multiracial society, but we must be monocultural. Australians must live under the one cultural umbrella,’ she said.

The Queensland senator pointed to the number of overseas students enrolled at Australian universities and the proportion of Australians born overseas as evidence that migration levels had become too high.

Citing Census data, Hanson said that 32 per cent of Australia’s population, about 8.8 million people, was born overseas.

She also highlighted figures showing that 51.5 per cent of Australians were either born overseas or had at least one parent born overseas.

‘Is that what is supported by the Australian electorate? Is that what Australia wants?’ Hanson asked.

She contrasted Australia’s demographic makeup with that of the United States, where she said the comparable figure was 14 per cent.

Hanson also raised concerns about language use in Australia, arguing that growing numbers of residents who speak languages other than English at home could undermine social cohesion.

‘Again, the 2021 Census showed that one in four people, or 23 per cent, speak a language other than English at home, the most common being Mandarin and Arabic,’ she said.

‘How can you generate social cohesion if people can’t speak the language?”

She said that 872,000 people reported speaking English ‘not well” or ‘not at all’ in the 2021 Census.

Hanson said multiculturalism had failed because it treated all cultures as equivalent to Australia’s own values and traditions.

‘Surely opposing that is not racist – it’s common sense,’ she said.

The One Nation leader concluded by reaffirming her party’s long-standing nationalist message.

‘My party is rightly called One Nation. It is clear what we stand for,’ Hanson said.

‘One nation, under one flag, and proudly Australian.’
