Nick Stevens (Year 10) and Jett Fisher (Year 11) are two of 32 WA students preparing to head to Turkey on Thursday.
Duncraig Senior High School is the only school with more than one participant in the annual Premier�s Anzac 10-day student tour.
57 students were selected from 1000 winning essays to take part in an interview to choose the final 32.
Jett said his essay was about the Anzac legacy and what it meant to young Australians.
�Gallipoli was the birth of Australia�s nationhood, as Charles Bean put it,� he said.
�From then it was no longer about Victorians, West Australians, Northern Territory; we were all Australians. It united us for the first time since Federation.�
Nick said the trip would be a once-in-a-lifetime experience.
�I�ve been told by people who went last year that it was an absolutely amazing experience and the centenary will be even more moving,� he said.
Mindarie Senior College teacher James McNeill is one of eight teachers selected for the tour.
Jack Ball (Mindarie Senior College), Tahlia Fenton (Mater Dei College), Jet-Rik Bernal (Girrawheen Senior High School), and Iluka teen Connor Shaw are also on the tour.
Duncraig Senior High School principal Stephen Spice said the school was honoured and proud of Nick and Jett�s achievements.
