Perhaps a bit of background for others. This young Australian Greens senator (in my view) comes across like an angry left wing Uni student. She is a little out of place, in a party that seems to be trying to become more mainstream. She used to be her party's spokesperson on all matters relating to immigration and boat people, which was an intense political issue. Back then, the Greens were the only significant party that was advocating letting all boat people arrive, and even rescuing them in their attempts.
About 3 or 4 years ago, there was a Senate committee where the military and the customs and border protection department were being grilled. Her questions as a senator revealed that she thought the fictional tv series, Sea Patrol, was some sort of real life reality show.
In relation to the "she only got 200 primary votes", it should be pointed out that these days, there are very few primary votes cast for senators. When voting for the senate, Australians can either number all the available candidates in order (from one to about 100) or simply vote "above the line" which means voting for a party and having preferences distributed as directed by that party. Most people can't be bothered and just vote "above the line".
