Protesters gathered in Sydney’s historic Rocks district on Saturday to rally against the New South Wales government’s plans to sell off the Sirius building – which contains 79 social housing tenants – to developers for more than $100m. The 1970s Brutalist building was nominated for heritage listing by the NSW National Trust in 2014 but the government has refused to grant it, saying the proceeds from the sale are needed to build more public housing elsewhere in Sydney
