A controversial sex education book for teenagers that was pulled from shelves in Australia has been given an unrestricted rating by our chief censor.

The classification means parents can decide for themselves if the book is right for their teenagers.

Family First spokesperson Sue Reid says they've got concerns around the age appropriateness.

She says the book is pitched at 14 year olds, but looks like a handbook and has juvenile animations.

"We don't think it is clearly targeted at the 14-year-old market- it's definitely aimed at a younger market and that's what we're concerned about."
