One Nation's Queensland party leader is heard boasting about how easy he found it to change laws, joking about what he'd do if he was rich and bemoaning Muslim immigration in dozens of conversations captured by an Al Jazeera covert investigation.
Two former Senate colleagues are engaged in a war of words, with the United Australia Party's Brian Burston levelling sexual harassment allegations at One Nation leader Pauline Hanson.

Federal Labor candidate Justine Keay wins the Braddon by-election in Tasmania, according to ABC election analyst Antony Green.
She's been accused of flip-flopping on policy and labelled the "most unstable senator" in years. Here's what Pauline Hanson has had to say about One Nation's stance on company tax cuts within the last 72 hours.

Since its spectacular debut in 1998 there have been 30 people elected to parliaments under the banner of Pauline Hanson's One Nation, but most didn't last a full term for the party.
Brian Burston will not be remembered as an ideological firebrand on the right-hand side of Australia's political spectrum, but his departure from One Nation leaves Pauline Hanson half as useful to the Government as she used to be.
The pair have been publicly bickering since Pauline Hanson sacked Brian Burston as the party's whip last month after she accused him of "stabbing her in the back" over company tax cuts.
