The Group of Twenty (G20) is the premier forum for international economic cooperation. 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, the United Kingdom, the United States, and the European Union. Each year, the presidency invites guest countries to participate. Spain is invited as a permanent guest.

The G20 brings together the world's major economies. Its members account for more than 80 per cent of world GDP, 75 per cent of global trade and 60 percent of the population of the planet.

The forum has met every year since 1999, 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.

• Indonesia holds the G20 presidency in 2022; an events calendar can be found on the official website.
• Italy hosted the G20 Leaders' Summit in October 2021 and leaders released the G20 Rome Leaders' Declaration.
• India will host the G20 in 2023, followed by Brazil in 2024.

Australia and the G20

Australia supports a strong and effective G20 to deliver coordinated international economic policies.. Australia works collaboratively and constructively with the G20 to support an open, global economy and the rules-based multilateral trading system. Australia and other G20 economies are focused on the need to support global economic and health responses to the pandemic and ensure a sustainable, inclusive and resilient recovery.

Australia published a summary of its implementation of G20 actions to support world trade and investment in response to COVID-19 (August 2021), as part of a commitment by G20 members to increase transparency and accountability.
