Prince George made his final Royal Tour appearance in Canberra as his parents bid farewell to Australia, completing their 19-day visit.
The royal family boarded a Royal Australian Air Force plane from Fairbairne Airbase in Canberra on Friday.
Dressed in a striking red cardigan, white shirt, red and white pinstripe shorts, white socks and black shoes, the nine-month-old George once again stole the spotlight.
The little prince was carried by his mum as William and Kate waved goodbye to the country.
And the future heir, who is always playful and smiling, looked a little grumpy and disgruntled to be leaving.
The Duke said that George tended to be grumpy on planes and particularly on long flights.
At the start of the royal tour, Kate had revealed that it took three days for George to get over his jet lag after 30-hour flight from London to Wellington, New Zealand.
The Duke and Duchess of Cambridge spent the last day of royal tour celebrating Australia and New Zealand Army Corps Day (ANZAC Day) at the Australian National War Memorial in Canberra.
On Friday, Australia and New Zealand marked the 99th anniversary of the first major military action involving Australian and New Zealand forces during the First World War.
At the memorial, the royal couple placed poppy flowers on the World War One Wall of Remembrance. They also attended a dawn memorial service.
