Wills also kept things stripped back and casual, dressed in chinos and matching shirt, as he was presented with a massive hunting spear to mark his visit to the academy.
Kate, on the other hand, was gifted a had-painted bracelet made of seed, which she was said to be "thrilled to receive" and was quick to put on her writs.
As usual, royal fans were out in force to welcome the couple as they touched down not far from Ayers Rock.
Amanda Bartels and her ten-month-old son Nathan made the five hour journey from Alice Springs to see the couple.
According to the Daily Mail they spoke to the Duchess who sympathised with the problems of keeping a baby occupied during the journey.
"She related to the trials of travelling," Amanda said. "She let Nathan play with her bracelet... And my daughter Aimee-Grace gave her some native flowers."
