The Prince of Wales has thanked the people of Papua New Guinea for the wonderfully warm welcome he and the Duchess of Cornwall have received.
"The welcome we received was so wonderfully warm and friendly and special that I promise you we shall leave here (on Monday) with immense regret but also with he shouts of welcome ringing in our ears," he said at a state dinner.
While in Boera village, the prince opened an aid post and planted a mangrove on the beach as part of a restoration project. The ABC reports it was his fourth visit to PNG.
"Quite a large proportion of ministers in the government here were only about one or two years old when I came here in 1966, which makes me feel even older," he said on Sunday night.
The prince also addressed the importance of Commonwealth, saying the body was based on friendship and relationships established over time and it was needed more today than ever.
The prince and his wife travel to Queensland, Australia, on Monday, as they continue a tour to mark the Queen's diamond jubilee, which concludes with next week's visit to New Zealand.
Longreach is the only Queensland destination on the tour. The royal couple are due to visit the Qantas Founders Museum where a new plane for the Royal Flying Doctor Service will be named.
