The Queen has held a rare face-to-face meeting with the Australian Prime Minister at Windsor Castle.
Dressed in a yellow floral dress, the Queen was photographed chatting to Scott Morrison at the Berkshire royal residence's Oak Room today.
She was seen smiling and looked relaxed as she spoke to the Australian PM.
A flat screen TV could be seen in the background of the room, amid the armchairs, cushions, antique furniture and bright red carpet.
The Queen, who is also monarch of Australia, mainly held virtual audiences since the start of the pandemic, with guests usually speaking to her via video-link from Buckingham Palace.
But the monarch, 95, has had several in-person engagements in the past week, from the G7 summit in Cornwall to Joe Biden's visit at the Castle.
In Cornwall, the Queen hosted an open-air reception at the Eden Project in Cornwall and was joined by the Prince of Wales, the Duchess of Cornwall and the Duke and Duchess of Cambridge.
Following the reception, the Queen carried out an engagement with Kate and Camilla where the monarch insisted on borrowing a ceremonial sword to cut a cake.
The Queen had been handed the sword by Edward Bolitho, the Lord-Lieutenant of Cornwall, for the task of cutting a large cake marking the Big Lunch at the Eden Project.
When told by an aide that there was a conventional knife available, the Queen replied: "I know there is, this is more unusual".
She then returned to Windsor for a mini Trooping the Colour to mark her 95th birthday before hosting tea for the US President and First Lady Jill Biden on Sunday.
The Bidens walked into the castle with the Queen via the Sovereign's Entrance at 5.18pm.
Mr Biden walked alongside the Queen who said to the president: "You completed your talks."
He replied: "Yes we did."
Before leaving the UK, Mr Biden, 78, shared details of his conversations with the 95-year-old head of state and revealed he had invited her to visit the White House.
He described the monarch as "very generous" and said they had a long talk.
Mr Biden added: "I don't think she'd be insulted but she reminded me of my mother.
"In terms of the look of her and just the generosity. She was very gracious."
He added he had invited the monarch to the White House, saying: "She said, 'What's it like in the White House?' I said, 'Well it's magnificent but it's a lot of people'."
Royal biographer Matthew Dennison said the monarch has long been used as the government's "secret weapon".
According to the author, she remained interested in the relationship between the UK and the US since meeting First Lady Eleanor Roosevelt in 1942, when she was still Princess Elizabeth.
Since then she has carried out four state visits in the US and met every US President since Dwight Eisenhower, with the exception of Lyndon Johnson.
