G20 members represent around 85 per cent of global gross domestic product, over 75 per cent of global trade, and two-thirds of the world’s population.
The members of the G20 are:
Argentina, Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Italy, Japan, Republic of Korea, Mexico, Russia, Saudi Arabia, South Africa, Turkey, United Kingdom, United States, European Union.
The G20 Presidency rotates annually according to a system that ensures a regional balance over time. Reflecting its nature as an informal political forum, the G20 does not have a permanent secretariat. Instead, the G20 President is responsible for bringing together the G20 agenda in consultation with other members and in response to developments in the global economy.
To ensure continuity, the Presidency is supported in this by the “troika”, made up of the current, immediate past and future host countries.
During Australia’s host year, the members of the G20 troika are Australia, Russia and Turkey.
