The review was carried out by professor Bill Louden from the University of Western Sydney after concerns over the program were raised by conservative MPs following a campaign in The Australian newspaper.

Birmingham announced several changes to the program, including amending some lesson plans, restricting certain resources to one-on-one counselling sessions between students and staff, and giving parents a greater say in whether their child accesses the program.

"Students should not be confronted with, nor be at greater risk of, accessing information or material that is inappropriate for their age or cultural background," Birmingham said.

Birmingham also indicated that the program would not continue to receive funding when the current plan ends in 2017.

"There was never an intention the program be funded beyond the current contract period," he said after being questioned in a press conference.

"The intention was what the program has done and is doing, developing resources for schools and teachers to use in accordance with their policies and following consultation with their parents and those resources will of course live on, on the Safe School hub website."

Shadow education minister Kate Ellis labelled the plan to end funding next year "sneaky and deceptive".
