The seventeen year-old student says the experience opened his eyes up to different cultures, religions, thought processes and made him see that stereotypes are not always as accurate as one might think.

"I made friends with a Kenyan guy who spoke Arabic as his first language and English as his second. He sat next to me on the bus. It could have been awkward but we started talking and he is one of the funniest people I have met in my life," Kieren said.

Kieren visited Washington, D.C. and New York during his time at the conference, and got to see the sights.

"The cruise on the Hudson River was a lot of fun, it gave us a chance to socialise and we got to see things like the Statue of Liberty up close," Kieren said.

The theory part of the conference included holding mock UN meetings, such as the General Assembly and UN Security Council.

Kieren learned a lot from the experience, and said he was surprised that he was one of the only public school students at the conference.

"Most of the Australian students were from private schools in Sydney or the Gold Coast," he said.

"It is strange how we are so different even though we are all from the same country."

Kieren has been motivated to travel overseas since his trip to America.

"It was an incredible experience, I am blessed to have the opportunity to go to the conference," he said.

Kieren would like to thank all of his supporters, especially the following few: Tony Ryan, Ros Ryan and Heather Ryan, for their work at the quiz night, and raising money for the trip.

Jim Williams from learn end legend, and his sponsor Stuart Glen.

He would also like to thank his mum, Beatrice Murray, for her endless support.

"I have learnt to look at the bigger picture, and to take people as individuals, I am so happy I had this experience," he said.
