A teacher who beat his children with a miniature cricket bat because he believed the Bible required him to do so can no longer legally work with children.

The teacher was convicted in August of two counts of recklessly causing injury and two counts of unlawful assault with an instrument against his three children, aged 12, five and three. He admitted to smacking their bare bottoms with a miniature autographed cricket bat, which he used to discipline them, on average, once a month.

The Deputy President of the Victorian Civil and Administrative Tribunal, Heather Lambrick, this week refused to set aside a decision to revoke the man's Working with Children check, which is required in order to work in any job related to children.

One of the man's children, a stepson, told his biological father about the assaults, who reported them to the police.

When the man - referred to as XXF - was interviewed by police, he said "we smack because it's part of our religious beliefs"
