After a public walk in Brisbane's CBD, the royals went to Lady Cilento Children's Hospital, where they were greeted by hundreds of staff and patients and made lamingtons. Stars Elizabeth Ross, 9, and Max Bishop, 12, from Juiced TV - a show made by and for children in the hospital - helped the couple make lamingtons. Prince Charles had a minor fumble when picking up the tongs before dipping the sponge cake into chocolate, prompting a kindhearted chuckle from his wife Camilla. Max asked Camilla if she had a favourite Commonwealth Games sport.

"She said she liked the swimming and when I asked her if she thought England had a chance she said she thought Australia would win the swimming," Max said. Their whirlwind tour of the hospital was guided by Abbi Head, 13, in a wheelchair, who said it was one of the most exciting experiences of her life. The teenager, who was diagnosed with bone cancer, said although she had a sick stomach, she powered through for the meeting. "It was a bit scary at first [but then] I started getting to know them and talking to them," Abbi said. Abbi, from Caboolture, said she joked with Prince Charles about playing the ukulele.

"He told me he played the cello ... a fancy ukulele," she said. "He had a little trouble with making the lamington." Prince Charles and Camilla make lamingtons at Lady Cilento Children's Hospital.

"I am happy I did it ... they were nice," Charlotte said. Charlotte said she was thrilled Camilla asked if she could keep the lyrics to her song. The royal couple were treated to a children's performance to Justin Timberlake's Can't Stop the Feeling. Camilla wore a pale green lace dress by Fiona Clare and a wide-brimmed Philip Treacy hat, while Prince Charles donned a light grey suit. Earlier, the couple were officially welcomed at Old Government House, signing the guest book and posing for an official photo.

Camilla smiled warmly at media as she realised she had been left holding her umbrella, but politely declined an offer from a staffer to take it off her hands. A 21-gun salute was fired from Kangaroo Point and Prince Charles inspected the royal guard of honour, taking some to stop and chat with an officer down the line. Despite intermittent rain, about 2000 people waited in the Brisbane City Botanic Gardens for hours, clasping Australian flags and flowers, hoping to catch a glimpse of the pair, showing support for the monarchy survived amid growing republican sentiment. The royals walked slowly walked past the crowds standing behind metal barriers, smiling as they stopped to shake hands and speak with many onlookers about everything from the Games, previous trips to Australia and people's children.

Chris Joyce, from Brisbane, spoke to Prince Charles about the weather. "I just said that it's been rather hot lately," Mr Joyce said. "He said 'thank goodness the [City Botanic] Gardens are still here and it hasn't been built on'." Girl Guide Annabel Lauder, 12, helped collect flowers handed to the royals, and said she was thrilled to meet the couple. "It's really daunting but a little exciting at the same time," she said.

"It's in the family," he said.
