G20 Brisbane: World leaders depart Japan's Prime Minister Shinzo Abe, pictured chatting to Prime Minister Tony Abbott at G20, will leave Brisbane today. Brisbane's bus and train network has returned to normal, as the final G20 world leaders prepare to leave the River City on Monday. The final leader is expected to depart by lunchtime, meaning drivers can expect to be hit with delays if they are caught to a passing motorcade. Japanese Prime Minister Shinzo Abe appears to be the first leader to leave on Monday morning. Police and a fleet of cars were waiting outside the Novotel in preparation about 6am. There was no time for sightseeing for most of the international leaders, with a majority flying out of Brisbane immediately after the summit concluded. Vladimir Putin - citing the need to catch some extra sleep - jetted out early yesterday afternoon before the official communique had been released. By late afternoon, the procession out of Brisbane began. For those not lucky enough to see Barack Obama in the flesh, the US President treated Brisbane residents to an impressive aerial show with Marine One and a host of support planes flying over the city to the Amberley RAAF base. He gave a quick farewell wave on the tarmac before boarding Air Force One. Meanwhile at the Brisbane Airport, planes for Brazil, Indonesia, Germany, Italy, South Africa, Mauritania, Argentina, New Zealand, China, Spain, France, Turkey and Canada departed. Australian Prime Minister Tony Abbott boarded a plane to Canberra. The extra 4000 police brought in to Brisbane began leaving on Sunday, with the final interstate members to leave on Monday.
