Abby East (13), Cameron Moffitt (14), Duncan Trevithick (14) and Sarah Langsbury (14) will represent New Zealand at the Australian All Schools Championships.
New Zealand Children's Athletics will take a team of 17 competitors and five managers.
The decision was made after it was established there was a group of young athletes who were too old to compete at the Pan-Pacific Games, to which NZ Children's Athletics is also taking a team.
Nominations were submitted for the team from around the country and the four Otago athletes were among those chosen.
Michael Moffitt, a Dunedin-based manager of the team, said the athletes were excited to be going to Australia.
''It's a huge opportunity for these kids to get a taste of international track and field.
''It's a bit different to running around the Cale' on a standard Saturday. It just gives them a bit of exposure to what might be in the future.''
All four athletes will compete in several events over the three days.
Moffitt, of Hill City-University, is entered in both the 100m and 200m hurdles, as well as the shot put and 4x100m relay.
Fellow Hill City-University athlete Trevithick will run the 100m, 200m and 400m sprints, as well as the 4x100m relay.
Langsbury, of Ariki, will compete in the 90m hurdles and 200m hurdles, as well as the long jump and high jump.
Wanaka's East, of the Aspiring Club, will run the 200m and 400m sprints.
The New Zealand Secondary Schools Athletics will also send a team to the meeting.
Two Otago athletes, Sam Gouverneur and Cameron Miller, have been selected in the squad of 27, which includes three reserves.
Both will compete in the under-18 boys grade.
