Strathfield North Public School holds a swimming carnival, cross country carnival and an athletics carnival each year. All students in Year 3 to 6 attend each carnival and students turning 8 years old in Year 2 may attend if they chose to. Students who finish in the top 3 for each event receive a ribbon and are invited to attend the zone carnival if they meet the criteria.
All students in K-2 participate in a fun run and a sports day on the cross country and athletics carnival days.
Parents are invited to attend all carnivals.
Every student at Strathfield North Public School is placed into a sports house and sports house captains from Year 6 are elected each year.
