Australia's recent prime ministerial merry-go-round has taken its toll on communication between world leaders at this week's G20 summit. Angela Merkel was reading up on Australia's latest leader, who took office just a few months ago, right in front of his eyes.

German Chancellor Angela Merkel was caught brushing up her knowledge on Australian Prime Minister Scott Morrison right before their meeting at the G20 summit in Buenos Aires. Merkel was photographed checking what appeared to be a list of background notes, which featured Morrison's mugshot.

The chancellor may have a reason to excuse herself: Morrison is the third Australian Prime Minister to visit a G20 summit in four years and the fifth PM in five years. He was sworn in in late August after local lawmakers ousted Malcolm Turnbull as the leader of the country and his own Liberal Party.

The revolving door of leaders in Australia has been the talk of the town.

Merkel's notes sparked curiosity among some, leaving Aussies guessing what the papers were saying about their prime minister.

Angela Merkel's trip to the world forum was more arduous than expected: her first attempt to visit Argentina this week failed after her flight had to make an emergency landing. According to reports in the German media, the government aircraft's entire communication system broke down, forcing the crew to cancel the flight just one hour after take-off. The chancellor then was forced to spend a night at a hotel in Bonn and fly to Buenos Aires via Madrid the following day, running late to the summit.
