Muslims want to impose Sharia law because they "hate Western society," Australia needs a "strong" leader like Vladimir Putin and the government must stop "blackmailing" parents into vaccinating their children, Pauline Hanson has told the ABC.

In the wide-ranging television interview, Pauline Hanson also backed Fair Work's cuts to penalty rates, warned her support for the Turnbull government's company tax cut plan is not guaranteed and urged rogue Coalition MP George Christensen not to defect to her One Nation party.

In her first appearance on the ABC's Insiders program, the Queensland senator also conceded her infamous 1996 warning that Australia was in danger of being "swamped by Asians" had not come to pass.

Senator Hanson - who will spend the next week in Western Australia as One Nation seeks to make gains at next weekend's state election - used the interview to ratchet up her attack on Islam and its followers, making no distinction between radical and moderate adherents of the religion.
