Staff and students at Terra Sancta College, Schofields are well versed in soccer.
A match between staff and year 10 students dominates school-yard conversation in the lead-up to the annual event, which sees players and spectators bond through a fun and friendly rivalry.
Head of mathematics Michael Knight organised the first match of what has become a school tradition in 2006.
He said everyone from the ground keepers and mathematics and history teachers to the principal get involved.
Boys and girls are generally picked from the school soccer teams to make up the student side.
"They'll be talking about it in the junior years," he said.
"They'll say 'I can't wait until it's my turn'.
"If a teacher misses the ball or if they score a goal it's just the same as if a student does.
"They'll be trying to pull off moves they've seen in the A-League and whether it comes off or not, everyone cheers.
"[The match is ] really to strengthen the relationship between staff and students."
The teams drew 1-1 after a student saved a penalty kick awarded to the teachers from becoming a deciding goal on October 11.
Brendon Muscat, 16, was part of the student team.
"Everyone was excited for the whole day, and energised," he said.
"It's probably a lot more fun [than playing competitively] because it's more relaxed and social," he said.
"It was a really enjoyable day. Hopefully the school keeps doing it."
