Australian Capital Territory voters are younger, more likely to hold a bachelor’s degree, and more likely to work in the public service than Australians generally. Their politics is mostly centre-left, and they have elected successive Labor and Labor–Greens governments since 2001. But urban issues are also prominent in this almost exclusively urban polity, and since the early 2010s, the government has combined an ambitious urban agenda centred around light rail and urban infill with more conventionally progressive social and environmental policies. This approach is particularly associated with Andrew Barr, Chief Minister since 2014, and it entailed risks for him and the Labor Party. Its success over the past decade represents a significant shift in ACT politics.
