The Australian colonies came together on 1 January 1901 with distinct histories of electoral system experimentation. Since Federation and the subsequent emergence of self-government for the territories, these subnational units have retained extensive control of their electoral systems. Continued electoral innovation at the subnational level has been able to address issues in electoral administration that have arisen in 21st-century society. This presentation explores state electoral innovations that have emerged in 21st-century Australia. Amidst global concerns of electoral disinformation, South Australia’s truth in political advertising law has seen renewed attention both at home and abroad. Political donation reform at the state level has also seen states such as New South Wales ban classes on donors and more stringent restrictions than the federal counterpart. Since 2025, there have been substantial changes and legal challenges to political donation regimes, with Victoria and Queensland particularly affected. Finally, the presentation examines the birth, proliferation and near-extinction of group voting tickets in subnational Upper Houses. In assessing state innovation, subnational politics emerge along a continuum of bold pioneers to recalcitrant pariahs on electoral reform.
