Not wanting to get into whether 45 is the right number, conceptually, I think clarity makes everybody happier, as well as including the review agencies. Moving goalposts is always a challenge.
To be clear, it's not unique to the IAA. It's not unique to the federal government. It's almost a time-honoured sport in this country to move goalposts in the approval regimes. However, there is a framework in this bill that allows some pragmatic, workable guidance that will give more clarity and more confidence.
To be clear, you cannot guarantee an approval. Sometimes, a firm “no” is better than an indefinite “maybe”.
