Australian Prime Minister and G20 host Tony Abbott has arrived in Brisbane, accompanied by British PM David Cameron.
The leaders shared a Royal Australian Air Force plane to the host city from Canberra where Mr Cameron addressed federal parliament earlier in the day.
Their plane touched down at Brisbane Airport shortly after 4pm AEST on Friday to a reception from Queensland Premier Campbell Newman and his wife Lisa.
The pair waved as they emerged side by side from the RAAF jet.
Mr Abbott is due at the B20 meeting on Friday night, which will bring together 27 business leaders from 18 countries.
The Australian prime minister is then expected to have dinner and bilateral talks with Indonesian President Joko Widodo, who flew into the country earlier on Friday afternoon.
The leaders of India, Japan, Mexico and South Korea also arrived in town on Friday, their planes landing at a special G20 terminal at the Brisbane International Airport.
Later on Friday night, three of the most power G20 leaders will arrive - China's Xi Jingping, Germany's Angela Merkel and Russia's Vladmir Putin.
