In short:

Newly-announced lead SA One Nation candidate Cory Bernardi says there is "no opposition" in South Australia ahead of the March 21 state election. 

One Nation leader Pauline Hanson told a press conference, where party supporters made several interjections during media questions, that Labor was "on notice".

What next?

She said she had not approached SA Liberals, including federal Liberal senator Alex Antic, to join the party ahead of the election.
