The Greens are fighting to hold onto their two Senate seats in South Australia, with the popularity of Nick Xenophon putting the chances of senators Sarah Hanson-Young and Robert Simms in jeopardy. A tipster wondered why Hanson-Young wasn’t campaigning in South Australia but could often be seen on Sky News — from the network’s Melbourne studios. Hanson-Young has been in Melbourne promoting the documentary Chasing Asylum, showing as part of the Human Rights Arts and Film Festival. The film includes never-before-seen footage of inside Australia’s offshore detention camps — and Hanson-Young was at the Adelaide premiere last night. We also hear that the Greens will soon bring out both the party’s former leaders — Bob Brown and Christine Milne — as part of the campaign across the country.
