It is compulsory for children to wear school uniforms at St Paul's. There are two uniforms:
- Formal Uniform - this uniform is worn two days per week
- Sports Uniform - is worn the remaining week days and features side panels in the allocated sports house colour.
The sports uniforms have coloured panels in them to distinguish the school house of each student.
Preparatory Year (Prep) students are required to wear only the sports uniform.
The school enforces a "no hat - no play" policy. The intensity of the sun in Queensland makes this a necessary rule of the school. All uniforms and approved socks, hair ties, homework pouches, hats and bags can be purchased at the school uniform shop.
