SIMON COURT (ACT): Minister, just going back to this clause 179, which inserts new section 81A: I was referring previously—and you did answer, thank you—to my question about new section 81A(3)(a) and new section 81A(3)(b). I need further clarification, because I think there's a very large gap between what new section 81A(3)(a) allows for—a liable parent would have to pay more if the assessment requires it. In this case, we're not talking about a private agreement between two parents who have separated amicably and have agreed on childcare arrangements for the children and have agreed on a division of responsibilities and who will be paying for certain things in the children's life, which would be wonderful, but it doesn't apply to most people who separate, which is why Inland Revenue compulsorily takes the liable parent contribution. That assessment of what a liable parent is required to pay actually is often determined by an Inland Revenue staff member acting in the role set out here. Their assessment is, essentially, full and final, so the liable parent, I understand, would find it very difficult to challenge or overturn an assessment because that's not what the system allows for. It's a very, very blunt tool.
