On Tuesday afternoon, final-year students and staff participated in a game of human chess, with students and staff dressing up and bringing props to match their piece.

And on Monday there was a game of netball between students and staff, which had plenty of controversy.

"There was a fair bit of cheating from the teachers," Year 12 student Harry Stansell laughed.

"I reckon they had a shorter hoop.

"The teachers always seem to have the advantage and win it every year. Of course they won it this year."

Fellow Year 12 student Archie Staines said the last-week celebrations are something he's been looking forward to for a number of years.

"It's something we always look forward to and it's always great to watch each year," he said.

"It's great in our final year that get to represent the school on our way out."

Science teacher Taylor Newton said the students get "really excited" for the last-week celebrations.

"Stannies makes a point to make the final week special and it shows how they have a strong relationship with the teachers," he said.

Year 12 students will continue their final-week celebrations on Wednesday, with a rugby match labelled 'brain versus brawn'.

While official school classes are over this week, all Year 12 students in NSW will be sitting their first Higher School Certificate exam next month on Tuesday, October 20, in either Standard or Advanced English.
