2023 was a year of consequence, at home and across the world. For Australia, the year was dominated by the Voice to Parliament, shifting security challenges, and the plight of everyday Australians grappling with a housing crisis, inflation and economic uncertainty. Globally we saw continuing war in Ukraine and deadly new conflict in Israel, ethical considerations of artificial intelligence and devastating reports on climate change. Working together, The Conversation's academics and journalists covered these issues and more, providing evidence-based research to help guide policy-makers and everyday Australians to make informed decisions at a pivotal time. This is a record of their work on the frontlines in this year of consequential decisions.
