The royal tour came to an end today as the Duke and Duchess of Cambridge and their nine-month-old son Prince George bid farewell to Australia.

After 19 days travelling down under, William and Kate were left "bowled over" by the warmth of the welcome from well-wishers, Kensington Palace said.

As the family fly back to the UK, here's a look back at the highlights of their tour of New Zealand and Australia.
