The University of Sydney's residential colleges, a number of which have come under fire for repeated sexual misbehaviour, will not be required to share the findings of an 18-month-long cultural review led by former sex discrimination commissioner Elizabeth Broderick with the university or students.

The review was triggered by a slew of incidents, including a female student at St John's being rushed to hospital after being forced by senior students to drink a mix of shampoo, sour milk, dog food, Tabasco sauce and alcohol, and the establishment of a "pro-rape" Facebook page by St Paul's students.

"Ms Broderick will provide a proposal to the university and the colleges to ensure effective and cohesive action, which builds on the independent cultural change programs underway at the colleges," a spokeswoman for the University of Sydney said.

"The university has previously committed to any report it receives as a result of the process being made public. Any material provided directly to the college is a matter for them."
