Australia will assume the chairmanship of the G20 on Sunday, giving it the key role in setting the agenda and managing the summit to be held in Brisbane next November.

The Brisbane summit, from November 15-16, is expected to attract 4000 delegates and 3000 journalists.
The first ministerial-level event leading up to the leaders' summit will be the finance ministers and central bank governors meeting in Sydney on February 21-23. Canberra will host a deputies-level meeting in January.
Cairns will host a second meeting of finance ministers and bank governors from September 20-21.
