This week, we chat to Shaun Carter from the Save Our Sirius Foundation about the fight to save Sydney's Sirius building. What does the future hold for it, and why is it so important to the city's heritage? We also talk about the citizenship scandal rocking Australian politics. Even after the High Court challenge last month, a number of politicians have been found to be dual citizens. Backchat hosts, Osman Faruqi and Sam Jonscher look into the issue, discussing the latest developments in the saga.
