This week polls showed, for the first time, One Nation ahead of the major parties and Pauline Hanson as preferred prime minister in second place ahead of Angus Taylor. 

Today we're talking about her strategy, her chances in the lower house and any parallels with the United States. Is it time to take Hanson seriously?

And the week would not be over if we didn't mention submarines - but second-hand ones this time. Was this always the intention as the government is saying? We'll unpick it.

Today's episode is hosted by Jacqueline Maley, with guests chief political correspondent Paul Sakkal, and foreign affairs and national security correspondent Matthew Knott.
