In terms of the potential JSCOT process and something coming back to parliament, who gets to decide whether it's a minor or a substantial change? Is the government the one that decides that? Is it a process where DFAT provide advice to you that they don't believe this needs to go through a political or a parliamentary process? Putting aside what you said about changes to the formula, can you step us through some examples of what might be minor or substantial processes? I'd be really interested in this. It sounds very subjective to me, so I'd like to be convinced on this.
