Dozens of world leaders gathered in Buenos Aires last week for the G20 summit, but Australia's Prime Minister Scott Morrison had a hard time being recognised.
Australia has had five Prime Ministers in the past eight years, and three different people have represented Australia as Prime Minister at the last four G20 summits - so it's no surprise some leaders needed a reminder of the current Prime Minister.
Leaders Mr Morrison met included US President Donald Trump, German Chancellor Angela Merkel, and French President Emmanuel Macron.

He admitted that Mr Trump asked him what happened to former Prime Minister Malcolm Turnbull.
Mr Morrison said he "just ran through what had happened," with Mr Turnbull when Mr Trump asked about the Australian government system.
"When you describe the parliamentary system, it's a foreign system to presidential systems and that's readily understood."
Photos also showed German Chancellor Angela Merkel holding a cheat sheet on Mr Morrison, complete with a photo of his face, during their one-on-one meeting.
Of all the leaders at the summit, Mr Morrison had been in the job for the shortest period of time - just over 100 days.
