Lake Bonney Concrete Slab

Mr WHETSTONE (Chaffey) (14:42): Supplementary, sir.

The SPEAKER: We will see if it is a supplementary.

Mr WHETSTONE: Minister, has the slab of concrete contributed to recent blue-green algae outbreaks in Lake Bonney?

The SPEAKER: Given you were reading the question, I will take it as a new question.

The Hon. S.E. CLOSE (Port Adelaide—Deputy Premier, Minister for Industry, Innovation and Science, Minister for Climate, Environment and Water, Minister for Workforce and Population Strategy) (14:42): I have no reason to think or evidence to suggest that that would be the case, but I am very happy to receive advice in order to determine whether that had any connection.
