"In some age-groups the qualifying standard is really quite high. In some of the age-groups maybe only between 12 and 20 have qualified, and the most that can is 30.
"We have several in the top 10, so they'll all be wanting to get into finals."
All 11 squad members are Wanganui High School students. Nine are from Lowe's age-group squad, and two - Elena Forlong and Fergus Smith - are from the Youth Squad.
It's been hard work. The Youth members train five times a week, the others train seven times in the water and three on the land.
"It's been a gradual development," said Lowe, who is in her seventh year of coaching. She has one more step to take with the squad, and that's another year away. It involves stepping-up the training to nine sessions a week.
"To be competitive they've got to be up to swimming at that level," Lowe said.
