“Hundreds of millions of people saw the Fifa matches around the world, and they also saw Papua New Guinea as a strong nation,” he said.
“When I was at Apec in Peru (two weeks ago), the leaders of other countries were asking about our Fifa tournament because they had seen it on television.
“We can be proud of the organisation that has gone into hosting the games and accommodating the players, officials and spectators who have come to watch the Fifa matches.”
The final last Saturday was won by North Korea which beat France 3-1. The 16 teams including PNG played their pool games over three weeks.
O’Neill said the nation was now looking forward to the next major events.
“PNG hosted a very successful Pacific Games last year, now a Fifa World Cup, and the Rugby League World Cup matches that will be played (here) next year,” he said.
“Then in 2018, the eyes of the world will be on us for an entire year when we host Apec, and invite the prime ministers and presidents of 20 countries to PNG.”
O’Neill said the citizens had been “the perfect hosts for the football world and outstanding ambassadors for the nation”.
“It was not the Government that hosted the Fifa World Cup, it was the people (of PNG) who hosted the Fifa World Cup, and you have all done us proud,” he said.
“The players and officials from around the world have been so impressed with our hospitality, our culture and our friendship.”
O’Neill also thanked the players and official of the 15 teams for coming to PNG.
“I thank you for being with our people and the bonds that you have developed with our communities,” he said.
O’Neill paid tribute to the PNG team which “put in a tremendous effort against the superpowers of women’s football”.
“On behalf of a proud nation, I thank you and I congratulate you for the heroic effort that you put in during your games,” he said.
“Every one of you served our nation with pride and distinction.
“You stood your ground against the best teams in the world and you earned their respect.”
