Wagga Wagga has recorded its first COVID-19 case in more than a year.
In a statement, Catholic education director Elizabeth O'Carrigan confirmed that a member of the Kildare Catholic College community had tested positive.
"The college has become non-operational from 2:00pm and for the remainder of today and tomorrow while contact tracing is conducted and deep cleaning of the school is undertaken," she said.
"We are working closely with Catholic Schools NSW and NSW Health to ensure the health and safety of all students and staff as a priority.
Ms O'Carrigan said although at this stage the situation only impacts the school, everyone should remain vigilant.
"Catholic Education, Diocese of Wagga Wagga and Kildare Catholic College will continue working with NSW Health and Catholic Schools NSW to ensure strategies are in place to address any developments," she said.
Get tested, get vaxxed
Murrumbidgee Local Health District said contact tracing interviews were underway and that any exposure sites would be listed as soon as they were identified.
"The advice for people who may have had contact with any member of the Kildare College community is to monitor for symptoms and get tested as soon as possible," it said in a statement.
Wagga Wagga City Council Mayor Greg Conkey echoed that call.
"We don't want it to spread throughout the community if we can avoid it at all, and I urge everybody, if they haven't been vaccinated, to please get vaccinated," he said.
"We've been in lockdown before and it has a significant economic impact on the city.
