QuestionView source ↗

I refer to Table 1 in the Perth Park Business Case Summary, which lists examples of new events for Western Australia to be hosted at Perth Park, including one Supercars event per annum (100% attributed as additional to the State), two mass participation events per annum (T100 Triathlon event and Tour Down Under warm-up, 100% attributed) and 10 commercial music events and five theatre and arts events per annum, with 50% attribution reflecting potential displacement from existing venues, and I ask: (a) For each event category in Table 1, what assumptions were used in the business case regarding: (i) total attendance per event; (ii) ticket prices and yield; (iii) proportion of attendees from within Perth, regional WA, interstate and overseas; and (iv) average length of stay and spend for interstate and international visitors; (b) Has the Government undertaken any analysis of the negative impact Perth Park may have on other WA venues and events—through displacement of shows, reduced utilisation, or reduced profitability—and, if so, will the Minister table that analysis; and (c) What contingency or risk adjustment has been applied in the business case for the possibility that: (i) the proposed Supercars event does not proceed at Perth Park; (ii) the T100 Triathlon or Tour Down Under warm-up events do not proceed; and (iii) these events are secured for only a limited number of years rather than across the full 30-year evaluation period?

(a)-(c) The Perth Park facilities are aimed at addressing gaps in the entertainment, sporting and community event infrastructure to attract new events.
The quantification method for net tourism benefits considers the number of events, the estimated attendance, the estimated percentage of out-of-state visitation, the average spend per trip, the percentage attribution to Perth Park and the existing tourism benefits. Out of state estimates and average spend per trip was informed by Tourism WA data.
ACIL Allen has undertaken sensitivity testing associated with both the upside and downside of the most significant or sensitive assumptions within the business case.
