That is true.
I would say that the solution put forward, the solution that we've recommended, is the one that we believe will future-proof it as it goes up or as it goes down. Hopefully it won't go back up, but we don't know what will happen in the future.
Having said that, the outcome is the main focus, and the outcome should be that there would be no disproportionate impact on people with a disability or on their families. If finance has another way of doing that, one that gets the same outcome, then we would certainly be happy with that.
