For a start, I always find the governments costings quite entertaining. I would like an explanation as to why it would double the cost. It is my understanding that families can access MBS child health checks. There is the requirement for the provision of additional health checks. I am wondering where that data is coming from when, as I understand it, families can access MBS child health checks. I do understand the issue around various states having different requirements and different health checks, but, firstly, why will it cost double; and, secondly, given your explanation of why they are so important, is that investment for additional families not worth while, given the importance of child health checks?
