While Australia is considered an energy superpower, Australian foreign policy has often overlooked energy diplomacy. Given the transformations taking place in global energy markets, the time is ripe to begin a policy discussion in Australia on energy diplomacy. I argue that Australian diplomatic efforts should broaden beyond a historical focus on promoting fossil fuels and securing export markets, to driving global energy governance reforms through the G20. This will not only help to ensure that the international energy architecture is capable of achieving governance objectives around energy security, energy access and climate change, but significantly, it will also help Australia to achieve broader foreign policy goals, such as ensuring emerging economies become responsible stakeholders within the international system.
