Pauline Hanson has called for a "monocultural" Australia as a protest crashed her first address to the National Press Club.
The One Nation leader also promised to boost regulation of AI, scrap SBS and make the ABC a subscription service in major cities as part of her wide-ranging speech.
She vowed to introduce nuclear energy into the national grid under a One Nation government, while also labelling segments of Islam a "social cancer".
But the speech was interrupted by a sign being lowered onto the stage that read: "I opposed a pay rise to workers".
Attendants quickly tore it down and allowed Senator Hanson to continue.
With One Nation rising in opinion polls to lead the major parties on primary votes, the firebrand senator said growing voter discontent with the status quo was behind the shift in the political landscape.
