This year 82 out of 158 Year 12 students are taking chemistry, and of last year's Year 13 graduates, 37 per cent are studying university subjects that employ chemistry knowledge including science, medicine and engineering.
Mr Torrie credited his teaching team for the popularity of the subject.
"Teachers here go to great lengths to point out to them why chemistry is really important in their every day lives and their futures."
Mr Torrie said he tried to personalise his teaching to each student.
"The attention span of students tends to be shorter these days, they are used to multi-media, social media, used to getting their information into really short bites.
"So you tend to have to break-up your lesson into lots of smaller chunks.
"It's important to capture their imagination first of all ... a lot of people consider chemistry as a hard subject, but it's a question of how it's taught and whether you are feeling positive about it in the first place."
