That included one year 3 student who was slapped with a short suspension, although students in years 8 to 10 were the most likely to get into trouble for illegal drugs.

There were 3766 prep and year 1 students suspended or expelled in 2018 for reasons including persistently disruptive behaviour, refusing to take part in classes, attacking adults or other children and verbal abuse.
