Journalist and former LNL correspondent Margo Kingston returns to reflect on how the rise of Pauline Hanson's One Nation in the late 1990's ultimately led to the split in the Coalition which has now manifested as the number of Teals and other independents in the Australian parliament. She also looks at the poltical influence of "Advance" and what effect they may have on the Dunkley by-election. 

Guest: Margo Kingston, journalist and author.
