❓ Ms. Brewer questions the robustness of the Perth Park Business Case, specifically regarding visitation numbers, downside risks, event numbers, and potential subsidies. The answer claims the Benefit Cost Ratio (BCR) is robust based on operational assumptions.

I refer to the sensitivity testing undertaken by ACIL Allen for thePerth Park Business Case Summary, and I ask:(a) How sensitive is the discounted Benefit Cost Ratio (BCR) to a change in visitation numbers for each event;(b) To what extent do the downside risks threaten the costs to exceed the benefits;(c) Was sensitivity testing undertaken on the number of events given as examples; and(d) Did sensitivity analysis account for potential subsidies to secure events?

(a)-(d)  The sensitivity analysis found the BCR to be robust, which included the number of events based on the operational assumptions in the business case.
