Several students at Kildare Catholic College are facing a reprimand after the school's scavenger hunt got out-of-hand last week.
It is understood a group of Kildare seniors made their way onto Wagga High School grounds after-hours on Thursday, allegedly causing damage to the school's property as part of the year group's 'muck up' traditions.
The school has condemned the actions, saying they were not sanctioned by the college executive.
"The Kildare Catholic College community is deeply disappointed in the misbehaviour of a number of year 12 students during a recent year 12 scavenger hunt," a spokesperson for the school said via a statement The Daily Advertiser.
"While the event may have been intended by the students as a community building activity, the misguided actions of a minority have no place in the culture of Kildare Catholic College."
Ahead of the event, the spokesperson said students "were addressed by staff and the police of possible consequences should there be misbehaviour".
Parents had also been advised that the school would not sanction the event "in any way".
A spokesperson for the NSW Department of Education confirmed "No Wagga High School students were involved in this matter".
It is not the first time students at the college have been reprimanded for actions during the muck up events.
In 2016 it was revealed a group of Kildare College students spray-painted fences, smashed glass and defecated inside Mater Dei Catholic College grounds.
In the aftermath of the latest pranks, the college has extended its apologies.
"The college apologises to the Wagga community for these regrettable events," the spokesperson said.
"The misbehaviour and anti-social actions of the few are not a true reflection of a year group who have been positive leaders for the College in 2020."
It is understood police have been made aware of the incident and the school has advised the students to make amends for the damage caused.
