In 1996 Pauline Hanson made her entry to parliament felt with an incendiary speech which declared Aboriginal Australians were given unfair advantages compared to non-Indigenous Australians - or "mainstream Australians" as she called them - and famously declared the country was being "swamped by Asians".

These particular groups garnered little attention in the speech officially marking her entry to the senate on Wednesday, but many of the same themes were there. In fact, Ms Hanson's speech used a direct callback to her "swamped" phrase to show her attention and fears have officially shifted from Asian Australians and Aborigines to Muslims.

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

A basic numerical word analysis of both speeches highlights this shift in her focus. In her 1996 speech, she made 12 mentions of the words "Aboriginal" and "Aboriginals" and two of "Asian" or "Asians".
