President, through you, I am advised that, as Senator Watt just indicated, this question probably ought to have been directed to me, as the Minister representing the Minister for the Environment and Water. If the senator wishes to continue otherwise, can I just indicate the opposition would give leave—the government would give leave—

Honourable senators interjecting—

I had a lot of years! The government would give leave for the supplementary to come to me, if it would be of any assistance.
