Four sets of parents have made it to the final where their parenting is stripped bare. Outside their comfort zone, families will be pushed to the very edge as the panel decides who has Australia's best parenting style.

It's the last round of challenges before the final, and American, Road School, Slow and Unstructured parents are ready to show us their best. Teaching self-control and independence is the focus as the kids try to find their way home, all by themselves. Only one set of parents can be chosen from this group to join the final challenge. But Dr Justin and Ally have a wild card to play.

The hot seat is switched for the last time as American, Road School, Slow and Unstructured parents step up to be the focus parents to prove their parenting styles are the best. When a delivery driver knocks on the door, will the children let them in?

Spiritual, Team, Stage and Influencer parents leave nothing in the tank as they show us how they give their kids skills to protect their lives and get them to face their fears. Another parenting finalist is chosen by the panel parents in the search for Australia's best parenting style.

A new group of parents become the focus parents. Spiritual, Team, Stage and Influencer parents face up to tantrums, confront social media for nine-year-olds and the ever increasing dangers of online graphic content.

Honest, Outback, Gentle and Lighthouse parents take on the next set of challenges, tackling bullying and facing the terror of losing a child. Continuing the search for Australia's best parenting style, our first finalist is chosen by the remaining parents on the panel.

The search for Australia's best parenting style begins with 12 sets of parents meeting to compare their approach and complete challenges that put their parenting styles to the test.
