Former teacher and ex-Liberal Party staffer Kevin Donnelly says Australian education has become too secular, and the federation's Judeo-Christian heritage should be better reflected in the curriculum.

The review was announced yesterday by Federal Education Minister Christopher Pyne, after concerns the curriculum had become too left-leaning and was failing students.

Mr Donnelly says religion does not have enough of a presence in Australia's "very secular curriculum", and that it needs to be taught "more effectively".

"I'm not saying we should preach to everyone, but I would argue that the great religions of the world - whether it's Islam, whether it's Christianity, Hinduism, Buddhism - they should be taught over the compulsory years of school," he said.
