As the premier forum for international economic cooperation, the Group of Twenty (G20) plays a critical role in steering the global economy through the significant challenges it faces.

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, Türkiye, the United Kingdom, the United States, the African Union and the European Union.

The G20 brings together the world's major and systemically important economies. Its members represent 85% of global GDP, 75% of international trade and around 80% of the world's population.

The forum has met every year since its inception in 1999 after the Asian Financial Crisis of 1997–98, with leaders meeting for an annual G20 Leaders’ Summit since 2008.

In addition to the Summit, ministerial meetings, sherpa meetings, working groups and special events are organised throughout the year.

• South Africa is holding the G20 presidency in 2025. An events calendar can be found on the G20 website.
• Brazil held the G20 presidency in 2024, with the Brazil Leaders’ Declaration released on 19 November 2024.
• The United States of America will host the G20 in 2026.

The G20 continues to play a significant role in shaping and strengthening global architecture and governance on all major international economic issues.

Australia and the G20

Australia supports a strong and effective G20 through which we can work to strengthen international cooperation on the major economic challenges facing the world. Australia works constructively with other G20 economies in pursuit of strong, sustainable, balanced and inclusive global economic growth.

Within the forum, Australia actively promotes an open global economy and a rules-based multilateral trading system.
