3.
The current brother school of St George Girls High School. The school is filled with perverts of all different kinds. Every year, they are forced to the "School Dance" where both Sydney Tech and St George are meant to "mingle" and be friendly.

Most people in St George do not go.

Although they have shortcomings (perverted, and an assortment of other words I'd rather not say) they have a really nice yearbook... Damn, why don't other schools get it?! Urgh.
St George Girl: Eeew. It's a Techie... Run AWAAAAAYYYYYY~!

Sydney Tech stands for Sydney Technical High School...
